band. These mixers are built with a unique "bilithic" Schottky-barrier diode chip and evaporated microstrip circuitry on alumina dielectric. Mixer noise figures are less than 7.5 db with local oscillator powers of
to 30 mw. The impedances are
in and out with the signal input VSWR being less than 1.5/1 over the local oscillator range and a bandwidth of
%.
