Custom MMIC launches IP3 mixers with low conversion loss and high LO-to-RF isolation up to 26GHz

© Semiconductor Today Magazine / Juno Publishing

Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA has launched a series of high-performance IP3 fundamental mixers.

The CMD253C3, CMD254C3 and CMD255C3 feature overlapping RF/LO frequencies spanning 6-26GHz, with each model demonstrating low conversion loss, high IP3 (third-order intercept point), high isolation, and wide IF bandwidth. The mixers are suited to use as upconverters and downconverters in demanding military, aerospace, and telecoms applications operating at C-band, X-band, Ku-band and K-band frequencies.

The series of mixers exhibits very high isolation from the RF and IF ports, in part due to an integrated and optimized balun structure. Each mixer can operate with LO drive levels as low as +15dB. With the addition of external hybrids and power splitters, the devices can be configured as image reject mixers or single-sideband modulators.

Conversion loss for the mixers is as low as 6dB, with LO-to-RF isolation as high as 48dB. Moreover, the device series offers LO-to-IF isolation that reaches 44 dB, and an RF-to-IF isolation as high as 30dB. The mixers are extremely linear, with input P2dB (output power for 2dB compression) typically around 15dBm, and an input IP3 as high as 24dBm.

The performance of these devices is extremely stable from -40℃ to +85℃. Each of these mixers is packaged in a 3mm x 3mm quad QFN surface mount package, and can be soldered using standard solder reflow processes.
