It is always a concern at high millimeter wave band that there is not enough power to drive the mixer, especially full waveguide band. Model FDB-XX-E1 series externally biased, balanced mixers is especially developed for this purpose. The mixers are offered in four waveguide bands to cover frequency spectra from 50 to 140 GHz. These mixers employ high performance GaAs Schottky beamlead diodes and balanced configuration to produce superior performance with a very low LO pumping level.
