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-compliant,
land grid array (LGA) package and can operate from −40°C to +105°C.
