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.
► 12-terminal, 2.25 mm x 2.25 mm, land grid array [LGA] package
APPLICATIONS
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.
► Industrial scanners
► Test and instrumentation
► Cellular infrastructure: 5G millimeter wave
► Military radios, radars, electronic counter measures (ECMs)
► Microwave radios and very small aperture terminals (VSATs)
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.
