Abstract: A modulator comprising two differential FET pairs, each pair having a current generator feeding the source electrodes thereof, a voltage source being coupled between the drain electrodes of each pair and the current generator. A low frequency signal is applied to one of the gate electrodes of each pair, ninety degrees out of phase with each other and a high frequency signal is applied to the other of the gate electrodes of each pair, ninety degrees out of phase with each other. The result is that all of the generated frequencies except one side band is cancelled at the drain electrodes of the pairs. The particular side band recovered is determined by the direction of the ninety degree phase shift between the signals.

Abstract: A monolithic distributed mixer includes a plurality of dual gate field effect transistors (FETs) and first and second corresponding pluralities of T shaped constant K-filters connected respectively to first and second gates of the dual gate FETs for delaying in time the LO and RF voltages applied thereto whereby the phase shift is the same at each filter and the phase difference between the LO and RF at each FET is equal. Thus, the IF energy developed at each drain is in phase. The plurality of dual gate FETs have their drains commonly connected for summing the IF outputs thereof to provide a flat response throughout the bandwidth which is limited only by the cutoff voltages of the FETs or first and second pluralities of K-filters which act as low pass filters.

Abstract: A push-push broadband dielectric resonator oscillator circuit that operates in the K and Ka band frequency range has two oscillator circuits that oscillate at the same fundamental frequency. An antiphaseal relationship is maintained between the two oscillators through the use of a dielectric resonator and the desired frequency is obtained by vectorially combining the output signals of the two oscillators that have the antiphase relationship to obtain an output frequency that is twice the fundamental frequency of operation of each of the individual dielectric resonator oscillator circuits.
