GENERAL DESCRIPTION

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 typical

insertion 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 for

continuous wave signals and 39 dBm average and 49 dBm peak for

long-term evolution (LTE) signals.

The ADRF5345 incorporates an integrated negative voltage gener-

applied to the VDD pin drawing a 2 mA supply current. The device

employs low voltage complementary metal-oxide semiconductor

(LVCMOS)-/low voltage transistor to transistor logic (LVTTL)- com-

patible controls.

The ADRF5345 comes in a 4 mm × 4 mm, 22-terminal, RoHS-com-

pliant, land grid array (LGA) package and operates between −40°C

to +105°C.
