Externally biased balanced mixers cover 50 to 140 GHz

It is always a concern at high millimeter wave band that there is not enough power to drive the mixer, especially full waveguide band. However, the Model FDB-XX-E1 externally biased, balanced mixer series is especially developed for this purpose.

The mixers are offered in 4 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.

The mixers are designed for full waveguide band operation with extremely wide IF bandwidth from DC to 18 GHz. The conversion loss measured is 11 to 15 dB for V band through F band with a typical LO power of 0 dBm and +5.0-Vdc/1.0-mA external bias.

These mixers are ideal candidates for test equipment, communication systems and EW receivers where broad band frequency down conversion is required.
