A technique that expands dynamic range (DR) of frequency down-converters in the C band frequency is presented. Primary characteristics of down-converter are evaluated to conflrm that it can be used in microwave receivers. The C band down-converter is carried out by the combination of RF mixers, band pass interdigital fllter, and X band combline fllter which are designed entirely for this project. Attainment of the perfect receiver is the flnal purpose of this paper, and a method that causes 72dB dynamic range, high tangential signal sensitivity and flne gain ∞atness is used for achieving the mentioned purpose. These efiorts improve the dynamic range about 19dB and gain ∞atness about 3.07dB.
