Subsequently, we present a number of attempts in the development of quasioptical functional components including complete receiver front ends and transceivers. 2. QUASI-OPTICAL MIXER PRINCIPLES Fig. 1 shows the basic diagram of the quasi-optical mixer. It should be recognized that the antenna is an integral part of the mixer and the «RF port» of the mixer is not accessible. The RF signal is captured by the antenna which is integrated into the mixer circuit. The local oscillator (LO) signal can also be captured by the same antenna although this is not an absolute requirement.
