GENERAL DESCRIPTION
► Input at ATTIN and ATTOUT
► 30 dBm typical steady state average
The ADRF5715 is a silicon, 1-bit digital attenuator with 16 dB
attenuation.
►
► 33 dBm typical steady state peak
The ADRF5715 operates from 1 MHz to 30 GHz with better than
► RF amplitude settling time (0.1 dB of final RFOUT): 6.5 µs typical
► Single-supply operation supported
► Tight in relative phase
1.15 dB of insertion loss and excellent attenuation accuracy. The
ATTIN and ATTOUT port of the ADRF5715 have an RF power
handling capability of 30 dBm steady state average and 33 dBm
steady state peak.
► No low frequency spurious signals
► CMOS-/LVTTL-compatible
► 12-terminal, 2.25 mm x 2.25 mm, land grid array [LGA] package
The ADRF5715 requires a dual-supply voltage of +3.3 V and −3.3
V. The device features complementary metal-oxide semiconductor
(CMOS)-/low voltage transistor to transistor logic (LVTTL)-compati-
ble controls.
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)
The ADRF5715 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 ADRF5715 RF ports are designed to match a characteristic
impedance of 50 Ω. The ADRF5715 comes in a 12-terminal, 2.25
mm × 2.25 mm, RoHS-compliant, LGA package and operates from
−40°C to +105°C.
