Custom MMIC, (, a developer of performance-driven monolithic microwave integrated circuits, announces the introduction of the CMD172, a new voltage-variable attenuator (VVA) in die form operating from 18 to 40 GHz.

Fabricated in GaAs with a small footprint, the CMD172 is a wideband absorptive VVA die that uses a single DC control voltage between -3 and 0 V to vary the RF signal level over a 37 dB dynamic range. The insertion loss of the CMD172 is only 1.6 dB. The GaAs MMIC also offers full passivation for increased reliability and moisture protection.

Ideal applications for the CMD172 include point-to-point and VSAT radio systems, microwave sensors, test instrumentation, and military and space applications.
