Abstract
An efficient wideband low noise microwave signal generator for active radars. Separate transmit drive (TD) and receiver local oscillator (LO) signals are generated by use of a single programmable reference generator and two frequency synthesized signals separated in frequency by an offset precisely equal to the transmit drive offset. The frequency synthesized signals are respectively summed and subtracted in frequency with the reference generator signal to obtain signals which may be selected as the TD and LO signals.
