Part details & applications

The ADRF5717 is a silicon, 2-bit digital attenuator with 48 dB attenuation range in 16 dB steps supporting glitch-free operation.

The ADRF5717 operates from 1 MHz to 30 GHz with better than 2.8 dB of insertion loss and better than 3.3 dB attenuation accuracy.

The ATTIN and ATTOUT port of the ADRF5717 have an RF power handling capability of a 30 dBm steady state average and a 33 dBm steady state peak.

The ADRF5717 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 ADRF5717 can also operate with a single positive supply voltage (VDD) applied while the negative supply voltage (V_DD) is tied to ground. See the Theory of Operation section for more details.

The ADRF5717 RF ports are designed to match a characteristic impedance of 50 Ω. The ADRF5717 comes in a 20-terminal, 3 mm × 3 mm, RoHS compliant, LGA package and operates from −40°C to +105°C
