RF109
2400 MHz Digital Spread Spectrum Transceiver
The RF109, a fully integrated transceiver device, provides the transmit, receive, and frequency synthesis functions for 2400 MHz digital spread spectrum systems operating in the 2400-2483.5 MHz portion of the ISM (Industrial, Scientific, Medical) band. The device has a direct conversion architecture that minimizes circuit complexity and cost. The receive path of the RF109 provides complete RF-to-baseband I/Q demodulation, including an LNA, double-balanced quadrature mixers, fully integrated baseband filters, and baseband variable-gain amplifiers. The transmit path is a variable-gain direct conversion modulator. Figure 1 shows the RF109's pin signals. Figure 2 shows the RF109 block diagram. The RF109 generates the Local Oscillator (LO) frequencies using a Phase Lock Loop (PLL) frequency synthesizer and an external 2.4 GHz Voltage Controlled Oscillator (VCO). The PLL provides a full frequency range of 2392.2-2505.6 MHz. The RF109 features low-voltage operation (3.0-4.5V) for low power consumption. A complete RF system solution for 2.4 GHz cordless telephone applications can be constructed with the RF109, a power amplifier, a differential 2.4 GHz frequency source and a Transmit/Receive (T/R) switch.

Technical Description
Receive Path_______________________________________ The LNA provides two gain levels for coarse Automatic Gain Control (AGC), which are selected via the LNAATTN control. The signal is down-converted to In-phase and Quadraturephase (I/Q) baseband signals using a matched pair of mixers and the LO. The receive baseband bandwidth has a bandpass characteristic. The I/Q baseband signals are internally low-pass and high-pass filtered to attenuate out-of-channel signals and to remove DC components. The low-pass cutoff is determined by the GmC filters and is set by the Rgmc resistor connected to pin 13. The high-pass cutoff is set by the value of the Cservo capacitors connected between pins 32-33, and pins 34-35. The baseband high-pass cutoff frequency should be set much lower than the low-pass cutoff frequency or else the servo loop will become unstable. The optimum receive bandwidth values are: fLPF = 820 kHz, Rgmc = 825 fHPF = 20 kHz, Cservo = 0.082 F A matched pair of VGAs provide fine AGC. The differential I/Q baseband signals are DC-coupled to the RXI+, RXI-, RXQ+, and RXQ- outputs, respectively. Transmit Path_______________________________________ The transmit path consists of an amplifier and a mixer. The mixer modulates the LO with baseband data supplied to pin 8. The transmit RF outputs from the RF109 are differential and matched for a 100 differential load. If a single-ended connection is required, then the unused output must be suitably terminated by a 50 resistor (as shown in Figure 5). The transmit output power is determined by the output power control inputs, PS1 (pin 21) and PS2 (pin 22), and by the value of Rmod (connected to pin 20). Rmod sets the bias current into the modulator which is then multiplied by a factor set by the state of PS1 and PS2. PS1 and PS2 input programming is given in the Transmitter Section of Table 3. LO Generation ______________________________________ The LO is generated by a programmable PLL frequency synthesizer and a 2.4 GHz external VCO. Synthesizer performance parameters are determined by the loop filter, the external reference oscillator, the sensitivity and phase noise of the VCO, and the frequency synthesizer programming. The RF109 requires differential inputs for VCO1 (pin 38) and VCO2 (pin 39). The typical differential input level is 200 mVp-p. A BALUN transformer, shown in Figure 5, is used to generate differential signals from a single-ended VCO output.

Synthesizer Programming____________________________ The frequency synthesizer block is comprised of a divide-by-3 counter (D), 9.6 MHz reference frequency (FREF) source, a fixed reference divider of 16 (R), 16/17 prescaler (M), a fixed counter of 83 (N), a programmable counter of 64 (A),an external loop filter, and a 2.4 GHz external VCO. The synthesizer can be programmed to cover 64 channels (channel spacing = 1.8 MHz) from 2392.2 MHz to 2505.6 MHz Table 1). The LO frequency is given by the following equation: fLO = (D) x (FREF/R) x ((M x N) + (A + 1)), where N > A. Example: fLO = 3 x (9.6 MHz / 16) x ((16 x 83) + 7) = 2403.0 MHz fLO = 3 x (9.6 MHz / 16) x ((16 x 83) + 46) = 2473.2 MHz Data Format. The synthesizer is programmed with a halfduplex 3-wire serial interface. The three signals are DATA, CLK, and STROBE. Each rising edge of the CLK signal shifts one bit of the data into a shift register. When the STROBE input is toggled from low to high, the data latched in the shift register is transferred to the A counter. The data format is as follows:
MSB S7 S6 S5 S4 S3 S2 S1 S0 LSB
Synthesizer Loop Filter. A typical loop filter design is shown below in Figure 3. The loop bandwidth is approximately 5 kHz with a nominal phase margin of 45 degrees for a VCO sensitivity of 60 MHz/V.

Power Management __________________________________ Independent power-up/power-down control of the transmit path, receive path, and frequency synthesizer is provided by the TXEN, RXEN and SYNTHEN controls, respectively. When all of the functions are powered down, the current drain from the voltage supply (Vcc) is at a minimum.
The timing relationship is shown in Figure 4. Programming bits S0 to S5, used for the A counter, are defined in Table 1. Bits S6 and S7 are reserved.

Recommendations on Layout and Implementation _______ A typical applications schematic is shown in Figure 5. Decouple all Vcc pins as close as possible to the supply pin. All ground pins should have minimum trace inductance to ground. If a ground plane cannot be provided right at the pins, the vias to the ground plane should be placed as close to the pins as possible. There should be one via for each ground pin. If the ground plane is at the bottom layer, it is recommended to have two vias in parallel for each ground pin. Connect all no connect (NC) pins to the ground. VCC1 (pin 6), VCC2 (pin 7), VCC3 (pin 25), and VCC4 (pin 31) should be connected to the common Vcc supply through individual decoupling networks. RTXD should be chosen to provide a typical baseband spread spectrum signal level of 0.10 Vp-p, to the TXD pin (pin 8). The routing of the trace to pin 3 (FREF) is very important to minimize the coupling of the reference clock (9.6 MHz) into the
VBAT 3V REGULATOR
CTRL GND1 BYP VCC GND2 OUT 47 pF 10 1000 + pF 47 F 8.2 pF
LO. The FREF trace should be well isolated from all other traces, preferably by grounded strips on either side of the trace. All traces from the VCO to pins 38 and 39 should be as short as possible with a characteristic impedance of 50 . Exposed Paddle Soldering ____________________________ The RF109 48-pin TQFP package has an exposed (metal) paddle on the bottom. The footprint dimensions of the exposed paddle are shown in Figure 6. The printed circuit board should provide through hole connections to the ground plane to ground the exposed paddle. The solder mask opening should have the same size as the exposed paddle. All relevant manufacturing considerations for this type of package should be taken into account. ESD Sensitivity______________________________________ The RF109 is a static-sensitive electronic device. Do not operate or store near strong electrostatic fields. Take proper Electrostatic Discharge (ESD) precautions.

Transmit Data. This input signal is used as the modulating signal. TXD is a single-ended, 1.2 Mbps NRZ signal from the baseband modem. The TXD signal shall be filtered first if any data/spectral shaping is desired. A resistor divider should be used to provide the desired signal level at the TXD input of the RF109. Tx Reference. This is the reference for the TXD input. It is AC-coupled to ground. Gain Control Reference. This is the reference for the gain control input. It is connected to ground. Received In-Phase Signal Negative, Received In-Phase Signal Positive. This differential signal pair is the in-phase portion of the baseband output of the receiver. The differential output signal level is typically 0.5 Vp-p, within the AGC operating range of 1.35-1.9 V. Received Quadrature Signal Negative, Received Quadrature Signal Positive. This differential signal pair is the quadrature portion of the baseband output of the receiver. The differential output signal level is typically 0.5 Vp-p, within the AGC operating range of 1.35-1.9 V. Auto Gain Control. This analog input signal is used to control the gain of the baseband VGAs in the receiver. This signal is generated by the baseband ASIC as part of the AGC control loop. An increase in the AGC voltage decreases the baseband VGA gain. The control loop provides a typical receive baseband differential signal of 0.5 Vp-p over the VAGC range of 1.35-1.9 V. Voltage Controlled Oscillator. This differential input provides the local oscillator signal from an external VCO to the RF109 mixers. An external BALUN may be used to convert a single-ended external VCO signal to the differential signals, VCO1 and VCO2, required by the RF109. The differential input signal level required is typically 200 mVp-p. Charge Pump Output. This output signal is used to control the external 2.4 GHz VCO. The CHPO current is typically 250 A. RF Input. This is the received RF input signal that is routed to the LNA of the RF109. This pin should be externally matched to 50 . The received signal must be AC coupled into LNAIN with a 12 pF series capacitor. RF Output. These are the differential transmit output signals from the RF109. The single-ended output impedance is 50 . The RF output signals are internally AC-coupled. The unused signal should be terminated to ground through a 50 resistor.
