Double-Balanced Fundamental Mixer offers high isolation.

Press Release Summary:

With 0.9 mm² die size, CMD179 general-purpose GaAs mixer can be used for up- and down-converting applications between 16 and 26 GHz. Conversion loss is 7 dB, LO to RF isolation is >40 dB, IF bandwidth is 8 GHz, and input IP3 is +18 dBm. Suited for hybrid assemblies, mixer can operate with LO drive level as low as +9 dBm; linearity and spur suppression will improve with increased drive. Suppression of spurious products is optimized due to ultra small, optimized balun structures.

Original Press Release:

New 16-26 GHz Double-Balanced Fundamental Mixer Offers High Isolation

Westford, MA – Custom MMIC, (, a developer of performance-driven monolithic microwave integrated circuits (MMICs) is pleased to announce the release of the CMD179, a fundamental mixer in die form.

The CMD179 is a general purpose, double-balanced GaAs mixer that can be used for up- and down-converting applications between 16 and 26 GHz. The mixer, which offers conversion loss of 7 dB, an LO to RF isolation of greater than 40 dB, an IF bandwidth of 8 GHz, and an input IP3 of +18 dBm, is ideally suited for hybrid assemblies given its small die size of 0.9 mm2.

A key advantage of the CMD179 is the very high suppression of spurious products due to the ultra small, optimized balun structures. The mixer can operate with an LO drive level as low as +9 dBm, though the linearity and spur suppression will improve with increased drive. Finally, two CMD179s can easily be configured as an image reject mixer or single sideband modulator with external hybrids and power splitters.

Ideal applications for the CMD179 are point-to-point and point-to-multipoint radios, test equipment, sensors, and military end-use.
