The ADRF5473 is a 6-bit digital attenuator with a 31.5 dB attenuation range in 0.5 dB steps manufactured in a silicon process attached on a gallium arsenide (GaAs) carrier substrate. The substrate incorporates the bond pads for chip and wire assembly, and the bottom of the device is metalized and connected to ground.

This device operates from 100 MHz to 40 GHz with better than 3.2 dB of insertion loss and excellent attenuation accuracy. The ADRF5473 has an RF input power handling capability of 26 dBm average and 31 dBm peak for all states.

The ADRF5473 requires a dual-supply voltage of +3.3 V and −3.3 V. The device features serial peripheral interface (SPI), parallel mode control, and complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatible controls.

The ADRF5473 is designed to match a characteristic impedance of 50 Ω.

Note that when referring to a single function of a multifunction pad in the data sheet, only the portion of the pad name that is relevant is mentioned. For full pad names of the multifunction pads, refer to the section.
