Non-Reflective Switch Offers High Isolation and Low Insertion Loss

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, announces the release of a new ceramic packaged, GaAs pHEMT MMIC Single Pole Double Throw (SPDT) Switch which is ideal for microwave radio, wideband telecom, electronic warfare (EW), industrial sensors, and test equipment applications from DC to 28 GHz.

The HMC547LC3 is a wideband, high isolation GaAs pHEMT MMIC SPDT switch which provides 40 dB isolation and less than 2 dB insertion loss at midband. The HMC547LC3 is controlled by two complementary logic inputs of -5/0V, and requires no DC bias supply. High input IP3 of +46 dBm and fast switching speed of 6 ns allow this switch to be used in numerous locations in advanced military and millimeterwave transceivers and subsystems.

The HMC547LC3 DC to 28 GHz SPDT Switch MMIC is housed in a ceramic 3 x 3 mm leadless surface mount package, and complements Hittite's broad line of single, double and multi-throw switches with frequency coverage to 86 GHz. For applications which require slightly less operating bandwidth, this same SPDT MMIC switch is also available in a 3 x 3 mm plastic QFN leadless package as the HMC547LP3E, and operates from DC to 20 GHz.

Samples of all SMT packaged products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
