Abstract
A frequency converter, incorporating a subharmonic mixer and a YIG tuned local oscillator filter in an integrated circuit configuration, provides improved conversion efficiency and ease of fabrication.
Claims5
A frequency converter comprising:
- (a) a subharmonic mixer having one RF, one IF and two LO ports, said mixer including two pair of antiparallel diodes with each diode pair being connected to one respective LO port,
- (b) a band-pass filter having an input port and a pair of output ports, said output ports being connected to the LO ports of said subharmonic mixer, and
- (c) a local oscillator signal source having an output port at which a number of signals at different frequencies are produced simultaneously, said source output port being connected to the input port of said filter to supply said mixer through said filter with an LO signal at a single frequency selected from said number of signals from said source.
