A MIXER FOR USE IN A MICROWAVE SYSTEM ABSTRACT OF THE DISCLOSURE The present invention relates to a mixer for use at high microwave frequencies (typically 21.8 x 23.2 GHz) in a low cost communication application. The invention utilizes low cost microwave components, including a low cost compartmented waveguide, shared by the signal and local oscillator and extensive microstrip circuitry. The provision of a pair of novel 1/4 wave impedance provides efficient antenna and local oscillator input filtering, and efficient coupling from the waveguide sections to the microstrip circuitry. The mixer oper- ation is carried out in the microstrip circuitry, which contains a hybrid coupler, a balanced diode detector, and the required mixer output filter. The arrangement is of low cost, and provides a low noise figure (7 db including the preamplifier), a good band selectivity (15 db return loss over the communications band), and low local oscillator radiation.
