GENERAL DESCRIPTION

The ADRF5716 is a silicon, 2-bit digital attenuator with 48 dB

attenuation control range in 16 dB steps, supporting glitch-free

operation.

This device operates from 100 MHz to 30 GHz with better than 2.9

dB of insertion loss and better than 1.5 dB attenuation accuracy.

The ATTIN and ATTOUT ports of the ADRF5716 have an RF input

power handling capability of 30 dBm average and 33 dBm peak for

all states.

The ADRF5716 requires a dual-supply voltage of +3.3 V and −3.3

V. The device features parallel mode control and complementary

metal-oxide semiconductor (CMOS)-/low voltage transistor to tran-

sistor logic (LVTTL)-compatible controls.

The ADRF5716 can also operate with a single positive supply

voltage (VDD) applied when the negative supply voltage (VSS) is tied

to ground. See the Theory of Operation section for more details.

The ADRF5716 RF ports are designed to match a characteristic

impedance of 50 Ω. The ADRF5716 comes in a 20-terminal, 3.00

mm × 3.00 mm, RoHS compliant, land grid array [LGA] package

and operates from −40°C to +105°C.
