MMIC Mixers Slice Conversion Losses

Custom MMIC’s CMD253C3, CMD254C3, and CMD255C3 IP3 fundamental mixers feature overlapping RF/LO frequencies spanning 6 GHz to 26 GHz, with each model demonstrating low conversion loss, high IP3, high isolation, and wide IF bandwidth. Suitable for use as upconverters and downconverters in military, aerospace, and telecommunications applications operating in the C-band, X-band, Ku-band, and K-band frequencies, the devices exhibit very high isolation from the RF and IF ports, due in part to an integrated and optimized balun structure. With the addition of external hybrids and power splitters, the devices can be configured as image reject mixers or single sideband modulators.


Other features include a conversion loss as low as 6 dB, LO-to-RF isolation as high as 48 dB, LO to IF isolation to 44 dB, an RF-to-IF isolation as high as 30 dB, input P1dB figures typically around 15 dBm, and an input IP3 as high as 24 dBm.
