GaN CMOS power switch delivers 40A to RF PAs

April 22, 2016 // By Graham Prophet
Specialist distributor RFMW has the 365CT000, 40A pulsed switch from Xsystor, Inc., that offers easy integration of GaN amplifiers in high speed, pulsed power systems.

These CMOS, complementary MOSFET switches have clocked speeds of under 200nsec for rise and fall times. Allowing source and drain voltages from 28 to 80V, the Xsystor switch is compatible with standard and high voltage GaN amplifiers and transistors. Operating temperature is specified for -40 to 85C but will withstand 175C with derated voltage and current capacity. The 365CT000 comes in a 23 x 27 mm, castellated SMT package allowing it to be placed on or near the voltage supply line's RF choke. Xsystor also offers inverting and non-inverting voltage controllers and sequencers for GaN implementations.
