SFB-15-E2 is a V-Band, externally biased balanced mixer. The mixer supports the full waveguide band operation for both LO and RF frequencies from 50 to 75 GHz with an extremely broad IF output from DC to 25 GHz. The mixer offers a typical conversion loss of 8 dB. The externally biased mixer is used when high LO power is not available. Externally biased mixer works with low local oscillator (LO) power of 0 to +5 dBm when external bias of +5 VDC is applied. As a trade-off, LO to RF isolation is lower compared to non-biased mixers.

To prevent damage due to accidental over-bias or reverse bias, voltage regulator M/N SOR-05-SM-R1 is highly recommended.
