New GaAs MMIC SP4T Reflective Switch Covers 23 to 30 GHzIdeal for Microwave Radio, SATCOM & Sensor Applications

Hittite Microwave Corp., the world class supplier of complete MMIC based solutions for communication & military markets, has introduced a new reflective, single pole four throw (SP4T) switch that is ideal for demanding applications requiring broadband performance, low insertion loss, fast switching speed and high power handling capability.

The HMC1084LC4 is a broadband reflective GaAs MESFET SP4T switch that provides frequency coverage from 23 to 30 GHz, and is controlled with 0/-3V logic. The HMC1084LC4 SP4T switch exhibits fast switching speed of 15 ns (rise and fall times) and consumes much less DC current than PIN diode based solutions. With an input signal of 30 GHz, the HMC1084LC4 exhibits 11 dB return loss, 26 dB isolation and only 2.8 dB insertion loss. Additionally, the HMC1084LC4  SP4T switch is capable of handling high power levels in excess of +27 dBm, that make it ideal for a wide range of applications including telecom infrastructure, sensors, microwave radio, SATCOM, antenna arrays and test instrumentation.

Housed in a compact leadless 4x4 mm ceramic SMT package and compatible with surface mount manufacturing techniques, the HMC1084LC4  SP4T switch complements Hittite’s extensive line of single, double and multi-throw MMIC switches with frequency coverage from DC to 86 GHz. Samples 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.
