Part details & applications

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 transistor logic (LVTTL)-compatible controls.

The ADRF5716 can also operate with a single positive supply voltage (V_DD) applied, and the negative supply voltage (V_SS) is tied to ground. See the Theory of Operation section in the data sheet 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 mm × 3 mm, RoHS compliant, land grid array [LGA] package and operates from −40°C to +105°C.
