Abstract

A double-balanced FET mixer may include: single-ended RF port that receives or delivers single-ended RF signal; RF balun that converts the received single-ended RF signal into differential RF signal or generates delivered single-ended RF signal from received differential RF signal; local oscillator input port receives local oscillator signal; direct IF port receives or delivers an IF signal; and at least two FETs process the local oscillator signal and generate or process the differential RF signal and IF signal. The mixer may have no IF balun separate and distinct from tRF balun; may receive an input signal at RF port and generates output signal at IF port. The mixer may receive input signal at IF port and generate an output signal at the RF port, the output signal in either case being plus or minus the local oscillator signal. The double-balanced FET mixer may operate with IF frequencies down to DC.
