GENERAL DESCRIPTION

The ADRF5141 is a reflective, SPDT switch manufactured in the

silicon process. The ADRF5141 is used in transmit and receive

applications with an integrated power limiter on the receive path.

The ADRF5141 operates from 6 GHz to 12 GHz. The RX arm with

the integrated power limiter has a flat leakage of 17 dBm with a low

insertion loss of 1.4 dB at 8 GHz to 11 GHz. The TX arm has an

insertion loss of 0.9 dB at 8 GHz to 11 GHz.

The ADRF5141 draws a low current of 13 μA on the positive supply

of +3.3 V and 360 μA on the negative supply of −3.3 V. The device

employs complementary metal-oxide semiconductor (CMOS)-/low

voltage transistor to transistor logic (LVTTL)-compatible controls.

The ADRF5141 requires no additional driver circuitry, making it

an ideal alternative to gallium nitride (GaN) and PIN diode-based

switches.

The ADRF5141 comes in a 20-lead, 3.0 mm × 3.0 mm, RoHS-com-

pliant, land grid array (LGA) package and can operate from −40°C

to +105°C.
