MMIC Switches

High Performance RF / Microwave GaAs MMIC Switches for SPST, SPDT, SP3T, SP4T, and SP5T Switching Requirements

Custom MMIC offers a wide array of SPST, SPDT, SP3T, SP4T, and SP5T RF / Microwave MMIC switches optimally designed to offer exceptional switch performance over an extremely broad frequency range from DC to 28 GHz (L, S, C, X, Ku, K, Ka band). These MMIC switches come in 2-way, 4-way and 5-way non-reflective and reflective switch designs with a low insertion loss and high port-to-port isolation. Switching speeds are as fast as 1.8 ns and some designs come with a built-in binary decoder to reduce the number of logic control lines. These MMIC switches take up minimal real estate in their leadless (surface mount) packages of 3x3 mm or 4x4 mm.

Among Custom MMIC's family of non-reflective switches and reflective switches, are microwave switches with switching speeds as fast as 1.8 ns. For added conveniences in circuit routing, several of the multi-throw switches come with built-in binary decoders, which reduce the number of logic control lines. The efficient and compact design of these MMIC switches enable the use of leadless surface mount technology (SMT) 3x3 mm QFN or 4x4 mm QFN packages. Several designs are also available as bare die.
