Description

The ADRF5721 is a silicon, 4-bit digital attenuator with a 30 dB attenuation control range in 2 dB steps.This device operates from 9 kHz to 40 GHz with better than 3.4 dB of insertion loss. The ATTIN port of the ADRF5721 has a radio frequency (RF) input power handling capability of 26 dBm average and 30 dBm peak for all states.The ADRF5721 requires a dual supply voltage of +3.3 V and ?3.3 V. The device features serial peripheral interface (SPI), parallel mode control, and complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatible controls.The ADRF5721 is pin compatible with the ADRF5731, the fast switching version, which operates from 100 MHz to 40 GHz.The ADRF5721 RF ports are designed to match a characteristic impedance of 50 ?.The ADRF5721 comes in a 16-terminal, 2.5 mm ? 2.5 mm, RoHS compliant, land grid array (LGA) package and operates from ?40?C to +105?C.Applications 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)
