Non-Reflective MMIC SP4T Covers DC to 18 GHz

 Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, announces the release of a GaAs pHEMT SP4T (Single Pole, Four Throw) MMIC Switch which is ideal for automotive, industrial sensors, test and measurement, microwave radio and military and space applications from DC to 18 GHz.

The HMC641 is a GaAs pHEMT SP4T MMIC chip which is rated for operation from DC to 18 GHz. This wideband, non-reflective SP4T switch exhibits 2 dB insertion loss and 42 dB isolation at midband, and features an on-chip binary decoder which requires only two control lines. High P1dB and input IP3 performance of +24 dBm and +40 dBm respectively, make the HMC641 ideal for applications requiring moderate to high linearity. This compact MMIC SP4T Switch requires no external matching components and occupies a footprint of only 1.9 x 1.6 mm. The HMC641 SP4T MMIC accepts control voltages of 0 and -5V with a fixed -5V supply, and draws only 3 mA.

The HMC641 complements Hittite's broad line of SPST and SPNT switch products which are available in die, SMT and connectorized module formats, with frequency coverage from DC to 86 GHz.
