The RFSW6124 is a GaAs pHEMT Single-Pole Double-Throw (SPDT) switch designed for use in cellular, 3G, LTE, and other high performance communications systems. It offers a high isolation symmetric topology with excellent linearity and power handling capability. The design is non-reflective such that RF ports 1 and 2 are terminated in the off-state. The enable pin allows for a terminated "all-off state". The RFSW6124 is 3V and 5V positive logic compatible.
