GENERAL DESCRIPTION

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 an isolation of higher than 31 dB.

The device has a radio frequency (RF) input power handling

capability of 26.5 dBm for both through path and hot switching.

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 operates from

−40°C to +105°C.
