The ADRF5345 is a high linearity, reflective, single-pole, four-throw(SP4T) switch manufactured in the silicon process.

The ADRF5345 operates from 1.8 GHz to 3.8 GHz with a typicalinsertion loss lower than 0.40 dB and a typical input IP3 of 84 dBm.

The device has an RF input power handling capability of 39 dBm forcontinuous wave signals and 39 dBm average and 49 dBm peak forlong-term evolution (LTE) signals

The ADRF5345 incorporates an integrated negative voltage generator(NVG) to operate with a single positive supply of 5 V (VDD)applied to the VDD pin drawing a 2 mA supply current. The deviceemploys low voltage complementary metal-oxide semiconductor
