GENERAL DESCRIPTION

The ADRF5714 is a silicon, 1-bit digital attenuator with 16 dB

attenuation, which supports glitch-free operation.

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

1.3 dB of insertion loss and excellent attenuation accuracy. The

ATTIN and ATTOUT port of the ADRF5714 has an RF input power

handling capability of 30 dBm average and 33 dBm peak.

The ADRF5714 requires a dual-supply voltage of +3.3 V and −3.3

V. The device features CMOS-/low voltage transistor to transistor

logic (LVTTL)-compatible control.

The ADRF5714 can also operate with a single positive supply

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

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

The ADRF5714 RF ports are designed to match a characteristic

impedance of 50 Ω. The ADRF5714 comes in a 12-terminal, 2.25

mm × 2.25 mm, RoHS compliant, LGA package and operates from

−40°C to +105°C.
