Hittite Microwave Corporation has introduced the HMC1084LC4 - A new reflective, Single Pole Four Throw (SP4T) switch which operates from 23 to 30 GHz and 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. This 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, it 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. The switch is housed in a compact leadless 4x4 mm ceramic SMT package and is compatible with surface mount manufacturing techniques.
