GENERAL DESCRIPTION

► P0.1dB insertion loss state: 30 dBm typical

► P0.1dB other attenuation states: 30 dBm typical

► IP3 insertion loss state: 51 dBm typical

► IP3 other attenuation state: 49 dBm typical

► High RF power handling

► Input at ATTIN and ATTOUT

► 30 dBm typical steady state average

► 33 dBm typical steady state peak

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 tran-

sistor logic (LVTTL)-compatible controls.

► RF amplitude settling time (0.1 dB of final RF_OUT): 6.6 μs typical

► Single-supply operation supported

► Tight distribution in relative phase

► No low frequency spurious signals

► Parallel mode control, CMOS-/LVTTL-compatible

► 20-terminal, 3 mm x 3 mm, land grid array [LGA] package

The ADRF5717 can also operate with a single positive supply

voltage (V_DD) applied while the negative supply voltage (V_SS) 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.

APPLICATIONS

► Industrial scanners

► Test and instrumentation

► Cellular infrastructure: 5G millimeter wave

► Military radios, radars, and electronic counter measures (ECMs)

► Microwave radios and very small aperture terminals (VSATs)
