Part details & applications

The ADRF5046 is a reflective, single-pole four-throw (SP4T) switch manufactured in the silicon process.

The ADRF5046 operates from 100 MHz to 44 GHz with insertion loss of lower than 3.0 dB and isolation of higher than 31 dB. The device has a radio frequency (RF) input power handling capability of 27 dBm for both the through path and hot switching at RFC pin.

The ADRF5046 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 ADRF5046 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 and instrumentation
Cellular Infrastructure – mmWave 5G
Military radios, radars, electronic counter measures (ECMs)
Microwave radios and very small aperture terminals (VSATs)
