Custom MMIC introduces two new broadband GaAs MMIC mixers

Custom MMIC of Chelmsford, MA, USA, a developer of performance driven monolithic microwave integrated circuits (MMICs), has introduced two new low loss, high linearity and high isolation MMIC mixers to its family of fundamental, IQ, and IRM mixers. CMD181 and CMD261 are general purpose double balanced mixers that can be used for upconversion and downconversion, or as image rejection mixers or single sideband modulators with the appropriate external hybrids and power splitters.

The CMD181 fundamental mixer’s RF and LO operates at 26-45GHz with a wide IF bandwidth of DC to 12GHz. With a low conversion loss of -6.5dB, the CMD181 MMIC mixer also features high LO to RF isolation of -37dB and LO to IF isolation of -29dB. This mixer is also highly linear, with an input IP3 of +22dBm.

The CMD261 mixer enables frequency band translation, with an RF range of 30-46GHz, an LO frequency range of 16-31GHz and an IF frequency range from 5-20GHz. With only -8dB conversion loss the CMD261 MMIC mixer also features high LO to RF isolation of -30dB and LO to IF isolation of -20dB. These new GaAs mixers are available in compact die form and can operate reliably from -55°C to +85°C.
