Hittite Microwave Introduced a New Broadband Reflective GaAs Mesfet

Hittite Microwave Corp of Chelmsford, MA, USA (which designs and supplies analog, digital and mixed-signal RF, microwave and millimeter-wave ICs, modules and subsystems as well as instrumentation) has introduced a new broadband reflective GaAs MESFET, Single Pole Four Throw (SP4T) switch, the HMC1084LC4.

HMC1084LC4 provides frequency coverage from 23 to 30 GHz, and is controlled with 0/-3V logic. The switch exhibits fast switching speed of 15 ns (rise and fall times) and consumes much less DC current than PIN diode based solutions, says the firm. 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 is capable of handling high power levels in excess of +27 dBm, making it suitable for applications such as 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 new switch complements Hittite's line of single, double and multi-throw MMIC switches with frequency coverage from DC to 86 GHz.
