<p>PROBLEM TO BE SOLVED: To provide a microwave band doubly balanced mixer circuit used for a microwave band, that prevents operation from becoming unstable due to the oscillation of the circuit itself. SOLUTION: In the microwave band doubly balanced mixer circuit of this invention, bases of each pair of transistors(TR) are placed closely for the connection in the shortest distance, common-mode local oscillation signals are applied to the bases of the pair of TRs, high-frequency amplifier signals with different phases are applied to the emitters of the pair TRs to mix the local oscillation signals and the high-frequency amplifier signals and to extract an intermediate frequency signal.</p> |
