High Power, 40 W Peak, Silicon SPDT, Reflective Switch, 8 GHz to 11 GHz

The ADRF5142 is a reflective single-pole, double-throw (SPDT) switch manufactured in the silicon process.

The ADRF5142 operates from 8 GHz to 11 GHz with a 1.2 dB typical insertion loss and a 40 dB typical isolation. The device has a radio frequency (RF) input power handling capability of 41 dBm average power and 46 dBm peak power for the insertion loss path.

The ADRF5142 draws a low current of 130 μA on the positive supply of +3.3 V and 500 μA on negative supply of −3.3 V. The device employs complementary metal-oxide semiconductor (CMOS)-/lowvoltage transistor to transistor logic (LVTTL)-compatible controls. The ADRF5142 requires no additional driver circuitry, which makes it an ideal alternative to GaN and PIN diode-based switches.

The ADRF5142 comes in a 20-lead, 3.0 mm × 3.0 mm, RoHS-compliant, land grid array (LGA) package and operates from −40°C to +85°C.
