Push-pull mixer for very high frequencies - is for conversion of gigahertz range signals into signals in VHF-UHF bands

摘要

It comprises a cavity resonator in which two H-oscillations of the signal to be converted and a signal from a local oscillator are excited, at 90 deg. to each other so that a push-pull mixed signal is generated in a diode pair in the resonator; matching means are provided for both signal input tuning. The resonator cavity is cylindrical, and the two signals are applied through its end faces, so that two orthogonal to each other H111 oscillations are excited; the matching means are exchangeably or adjustably inserted into the resonator; a coupling plate with coupling slots for the signals is provided at each end of the cylinder.
