Part details & applications

The ADRF5047 is a reflective, single-pole, four-throw (SP4T) switch manufactured in the silicon process.

The ADRF5047 operates from 9 kHz to 44 GHz with an insertion loss of lower than 2.7 dB and isolation of higher than 31 dB. The device has a radio frequency (RF) input power handling capability of 26 dBm for both through path and hot switching at RFC.

The ADRF5047 draws a low current of 3 μA on the positive supply of +3.3 V, and −110 μA on the negative supply of −3.3 V. The device provides complementary metal-oxide semiconductor (CMOS)-/low voltage transistor-transistor logic (LVTTL)-compatible controls.

The ADRF5047 is pin-compatible with the ADRF5046, fast switching version, which operates from 100 MHz to 44 GHz.

The ADRF5047 comes in a 20-terminal, 3 mm × 3 mm, RoHS-compliant, land grid array (LGA) package and can operate from −40°C to +105°C.

Applications

Industrial scanner
Test instrumentation
Cellular infrastructure—mmWave 5G
Military radios, radars, and electronic counter measures (ECMs)
Microwave radios and very small aperture terminals (VSATs)
