| RF2361 3V LOW NOISE AMPLIFIER/ 3V PA DRIVER AMPLIFIER Package Style: SOT 5-Lead Features Low Noise and High Intercept Point Adjustable Bias Current Power Down Control Single 2.5V to 6.0V Power Supply 150MHz to 2500MHz Operation Extremely Small SOT 5-Lead Package RF IN 1 5 GND2 GND1 2 VPD 3 4 RF OUT Applications TDMA/CDMA/FM Cellular PCS LNA Low Noise Transmit Driver Amplifier General Purpose Amplification Commercial and Consumer Systems Functional Block Diagram Product Description The RF2361 is a low noise amplifier with a very high dynamic range designed for digital cellular applications. The device functions as an outstanding front end low noise amplifier or power amplifier driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a concern. When used as an LNA, the bias current can be set externally. When used as a PA driver, the IC can operate directly from a single cell Li-ion battery and includes a power down feature that can be used to completely turn off the device. The IC is featured in a standard SOT 5-lead plastic package. NOTE: The RF2361 is a non-Pb-free product. If a Pb-free product with the same functionality and package is desired, please see the RF2878.

Rev A10 DS070731 RF2361 Pin 1 Function RF IN Description RF input pin. This pin is DC coupled and matched to 50 at 836 MHz. Interface Schematic To Bias Circuit RF OUT RF IN 2 3 GND1 VPD Ground connection. Keep traces physically short and connect immediately to ground plane for best performance. For low noise amplifier applications, this pin is used to control the bias current. See plots for bias current settings. An external resistor (R1) can be used to set the bias current for any VPD voltage. For driver amplifier applications, this is the Power Down pin for the IC. VPD =2.8V +/- 0.1V is required for proper operation. VPD< 0.9V turns off the Part. External RF bypassing is required. The trace length between the pin and the bypass capacitors should be minimized. The ground side of the bypass capacitors should connect immediately to ground plane. Nominal current required for VPD =2.8V is 2.0mA typical and 3.0mA Max (@ VPD =2.9V). PD 4 RF OUT 5 GND2 Amplifier Output pin. This pin is an open-collector output. It must be biased to either VCC or pin 4 through a choke or matching inductor. This pin is typically matched to 50 with a shunt bias/matching inductor and series blocking/matching capacitor. Refer to application schematics. Ground connection. Keep traces physically short and connect immediately to ground plane for best performance.

Typical thickness is 3inch to 8inch gold over 180inch nickel. PCB Land Pattern Recommendation PCB land patterns are based on IPC-SM-782 standards when possible. The pad pattern shown has been developed and tested for optimized assembly at RFMD; however, it may require some modifications to address company specific assembly processes. The PCB land pattern has been developed to accommodate lead and package tolerances. PCB Metal Land Pattern A = 0.70 x 1.00 (mm) Typ. Dimensions in mm. Pin 1 Pin 5 A 0.95 Typ. A A 1.90 Typ.

Rev A10 DS070731 RF2361 PCB Solder Mask Pattern Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the PCB metal land pattern with a 2mil to 3mil expansion to accommodate solder mask registration clearance around all pads. The center-grounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask clearance can be provided in the master data or requested from the PCB fabrication supplier. A = 0.90 x 1.20 (mm) Typ. Dimensions in mm.
