ABSTRACT:
A microwave signal frequency multiplier is used to produce a harmonic signal derived from a microwave pump signal. In a selected embodiment, a Ka pump signal is converted to a W band microwave signal. The frequency signal multiplier includes a housing having a signal input port and a harmonic signal extraction port. The interior of the housing comprises a pump signal cavity which is tuned to the pump signal. Within the pump signal cavity, there is provided a non-linear material which converts the pump signal to a harmonic, preferably a third harmonic, of the pump signal. A frequency selective barrier within the pump signal cavity defines a harmonic signal cavity. An extraction port is coupled to the harmonic signal cavity for removing the harmonic signal from the multiplier. The frequency selective barrier is essentially transparent to the pump signal but is reflective to the harmonic signal. A preferred embodiment for the non-linear multiplier for producing the harmonic signal is a doped semiconductor superlattice. The frequency selective material may also be fabricated as a superlattice.
