Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA has launched two gallium arsenide (GaAs) high-IP3 I/Q mixer MMICs covering the C- and X-bands.

The CMD257C4 and CMD258C4 feature wide IF bandwidths and what is claimed to be excellent image rejection, compact 4x4 SMT packages and cost savings compared with hybrid image reject mixers and single-sideband upconverter assemblies.

The CMD257C4 offers a wide IF bandwidth from DC to 3.5GHz, and an RF & LO bandwidth of 6-10GHz. It features image rejection of 31dB and a low conversion loss of 5.2dB.

The CMD258C4 delivers image rejection of 29dB and a low conversion loss of 5.5dB. Its RF & LO range also covers C-band and X-band frequencies, from 7.5GHz to 13GHz, with a wide IF bandwidth of DC to 3.5GHz.

Both the CMD257C4 and CMD258C4 can be used as either image reject mixers or single-sideband upconverters, and are composed of two double balanced mixer cells and a 90° hybrid. An external IF hybrid is needed to complete the image rejection.

The MMIC mixers come in leadless surface-mount packages, and are designed to operate within specification from -40℃ to 85℃.
