Abstract
A four-port dual mode microwave mixer which operates without IF or RF switches and which provides both a passive mode of operation wherein the mixer operates as a lossy frequency translator when driven by a offset signal generator, and an active mode of operation wherein the mixer is used to convert a modulated received signal to an intermediate frequency which is mixed with the offset signal in a phase detector to detect the modulation which is used through a phase-locked loop to slave the local oscillator for retransmission of a translated signal with gain.
