6 / 7 page  6 Biasing and Operation The AMMP-6522 is normally biased with a positive drain supply connected to the Vd pin and a negative gate voltage connected to the Vg pin through bypass capacitors as shown in Figure 17. The recommended drain supply voltage is 4 V and gate bias voltage is -1V. The corresponding currents are 75 mA and 0.1 mA re- spectively. The typical required LO level is +15 dBm and it should come from a low noise driver to ensure that overall Front End NF is low. The image rejection performance is dependent on the selection of the IF quadrature hybrid. The performance of the IF hybrid as well as the phase balance and VSWR of the interface to the AMMP-6522 will affect the overall front end performance. There is minimal performance degradation if Vdd is lowered to 3 V or raised to 5 V. If lower current is re- quired, then Vd = 3 V will provide considerably similar RF performance. Figure 17. Application of receiver with IF Balun The recommended Vg is -1 V. However, depending on the operating frequency, Vg can be changed to achieve better performance for that particular frequency. Please refer to Figures 9 and 10 for how to best select the appropriate Vg for the intended frequency of operation. Theoretically IF frequencies can be as low as DC. However, when direct conversion is used (IF = DC), a so-called phenomenon DC-offset could occur at the two IF outputs. In most practical applications, IF should be more than a few hundreds kHz to avoid DC-offset cor- rection. Refer the Absolute Maximum Ratings table for allowed DC and thermal condition.
