VDI offers subharmonically-pumped mixers (SHM) and even-harmonic mixers (EHM) for a variety of applications between
50 GHz and 1700 GHz. These mixers use only planar and/or integrated diodes and provide state-of-the-art performance.
VDI SHMs ( LO = ½ RF frequency) have a waveguide LO input, are easy to use and ideally suited for mmWave & THz applications. These mixers can be used to up or down convert signals. The subharmonically-pumped mixers have a separate LO waveguide flange and typically exhibit > 100 dB isolation of the LO at the RF port.
