| HMC500LP3 / 500LP3E v01.0705 GaAs HBT VECTOR MODULATOR 1.8 - 2.2 GHz Typical Applications The HMC500LP3 / HMC500LP3E is ideal for: * Wireless Infrastructure HPA & MCPA Error Correction * Pre-Distortion or Feed-Forward Linearization * PCS, GSM and W-CDMA Systems * Beam Forming or RF Cancellation Circuits 3 x 3 mm QFN Plastic Package Features 360 of Continuous Phase Control 40 dB of Continuous Gain Control -162 dBm/Hz Output Noise Floor +33 dBm Input IP3 Functional Diagram General Description The HMC500LP3 & HMC500LP3E are high dynamic range Vector Modulator RFICs which are targeted for RF predistortion and feed-forward cancellation circuits, as well as RF cancellation and beam forming amplitude/phase correction circuits. The I & Q ports of the HMC500LP3 & HMC500LP3E can be used to continuously vary the phase and amplitude of RF signals by up to 360 degrees and 40 dB respectively, while supporting a 3 dB modulation bandwidth of 150 MHz. With an input IP3 of +33 dBm and input noise floor of -152 dBm/Hz (at -10 dB maximum gain setting), the input IP3/noise floor ratio is 185 dB. 13 MODULATORS - SMT Electrical Specifications, TA = +25 C, Vcc= +8V Parameter Frequency Range Maximum Gain Gain Variation Over Temperature Gain Flatness Across Any 60 MHz Bandwidth Gain Range Input Return Loss Output Return Loss Input Power for 1dB Compression (P1dB) Input Third Order Intercept (IP3) Output Noise Control Port Bandwidth (-3 dB) Control Port Impedance Control Port Capacitance Control Voltage Range Group Delay Over 60 MHz Bandwidth Supply Current (Icq) 13 -14 Min.

Gain and Phase control are applied through the I and Q control ports. For a given linear gain (G) and phase () setting, the voltages applied to these ports in all measurements are calculated as follows: G Cos ( ) G max G Q (G, ) = Vmq + 1.0V Sin ( ) G max I (G, ) = Vmi + 1.0V Where Vmi and Vmq are the I and Q voltage settings corresponding to maximum isolation at room temperature and F = 2 GHz. Note that G=10X and Gmax = 10Y where x = Gain Setting ( dB ) and 20 y= Max Gain Setting( dB ) . 20 Nominally Vmi = Vmq = 1.5V, Gmax = 0.316.

Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation board should be mounted to an appropriate heat sink. The evaluation circuit board shown is available from Hittite upon request.
