ABSTRACT:
A stripline tuning fork microwave balanced mixer circuit which includes two diodes (21, 22) and a differential transformer (61) whereby matching is accomplished in the differential transformer (61) and in the circuit arrangement between the differential amplifier and the diodes (21, 22) for matching the resistance to the input terminals (1, 2) and a transforming circuit (24, 25, 26) which suppresses the frequency range of the input signals following the diodes and has simultaneous high frequency blocking for matching to the intermediate frequency signal output at terminal (3). This latter circuit can be utilized so that it functions as a blocker for the sum frequencies of the two input signals and the balanced push-pull mixer circuit of the invention can be used in sensitive receivers used in the microwave range.
