NOTES:
4. Required external resistor for Mixer biasing. Value optimized for 2.7mA bias current with R = (V_CC - 0.93)/2.7mA. Most Mixer cell characteristics
like Gain, NF etc., can be affected when biasing is outside the optimum value.
5. The combination of these attenuator pads and the Band Pass Filter insertion loss shall bring the overall Cascaded Gain at the desired frequency
of operation from 21dB to 22dB for best performance. The selection of these values is optional. The total gain, LO feedthru, Mixer and Pre-
amplifier interaction (stability) and output compression point performances can be manipulated according to the user needs.
