New 6 GHz to 26 GHz Mixer Series Offers Low Conversion Loss and High LO to RF Isolation

Custom MMIC has introduced a new series of high performance IP3 fundamental mixers, the CMD253C3, CMD254C3, and CMD255C3. This new series features 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.

The mixers are well suited for use as up-converters and down-converters in demanding military, aerospace, and telecommunications applications operating in the C-band, X-band, Ku-band, and K-band frequencies. They exhibit very high isolation from the RF and IF ports, in part, due to an integrated and optimized balun structure. Each of these mixers can operate with LO drive levels as low as +15dB. With the addition of external hybrids and power splitters, they can be configured as image reject mixers or single sideband modulators.

Conversion loss for the mixers is as low as 6 dB, with LO to RF isolation as high as 48 dB. Moreover, the device series offers a LO to IF isolation that reaches 44 dB, and an RF to IF isolation as high as 30 dB. They are extremely linear, with input P1dB figures typically around 15 dBm, and an input IP3 as high as 24 dBm. The performance of these devices is extremely stable from -40 ℃ to +85 ℃. Each of the mixers is packaged in a 3mm x 3mm quad QFN surface mount package, and can be soldered using standard solder reflow processes.
