GENERAL DESCRIPTION

The ADRF5721 is a silicon, 4-bit digital attenuator with a 30 dB

attenuation control range in 2 dB steps.

semiconductor (CMOS)-/low voltage transistor to transistor

logic (LVTTL)-compatible controls.

This device operates from 9 kHz to 40 GHz with better than 3.4 dB

of insertion loss. The ATTIN port of the ADRF5721 has a radio

frequency (RF) input power handling capability of 26 dBm

average and 30 dBm peak for all states.

The ADRF5721 is pin compatible with the ADRF5731, the fast

switching version, which operates from 100 MHz to 40 GHz.

The ADRF5721 RF ports are designed to match a characteristic

impedance of 50 Ω.

The ADRF5721 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

The ADRF5721 comes in a 16-terminal, 2.5 mm × 2.5 mm,

RoHS compliant, land grid array (LGA) package and operates

from −40°C to +105°C.
