High Performance Subharmonic Mixers

Our Sub Harmonic Mixer are based on zero-bias balanced anti-parallel planar Schottky diodes and are suitable for all types of heterodyne detection systems with the advantage of the local oscillator operating at one half of the target frequency.




Common specifications for all Subharmonic Mixers (narrowband) in this series:
