Abstract
An improved, dual frequency transmit-receive module operable for use with two harmonically related frequencies. This dual frequency transmit-receive module utilizing; a push-pull class B power amplifier having dual output ports, a standard frequency mixer and a harmonic mixer, is operable to transmit or receive an original frequency as well as a second harmonic of that same frequency, simultaneously or at distinct, discrete intervals. This improved dual frequency transmit-receive module is operable in any radar system, using only one, or a multiplicity of antennas. However, this transmit-receive module has specific application to active aperture radar systems utilizing one antenna means for each individual transmit-receive module in an active antenna array.
