ABSTRACT:
A wideband frequency synthesized, fault-tolerant microwave signal generator is described, which can generate the spectrally pure transmitter or antenna drive and receiver first local oscillator (LO) signals needed for advanced tactical airborne radar systems. Separate generation of the transmitter drive (TD) and first LO minimizes spurious signal generation over a wide operating band, typically 45% or greater. Extensive fault tolerance is provided without resort to redundant hardware. The sharing of two internal signal generators limits the frequency generation needs to just the operating band for economy of required hardware.
