Description

The ADRF5720 is a silicon, 6-bit digital attenuator with 31.5 dB attenuation control range in 0.5 dB steps.This device operates from 9 kHz to 40 GHz with better than 4.5 dB of insertion loss and excellent attenuation accuracy. The ATTIN port of the ADRF5720 has a radio frequency (RF) input power handling capability of 27 dBm average and 30 dBm peak for all states.The ADRF5720 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 ADRF5720 is pin-compatible with the ADRF5730, the fast switching version, which operates from 100 MHz to 40 GHz.The ADRF5720 RF ports are designed to match a characteristic impedance of 50 ?. For wideband applications, impedance matching on the RF transmission lines can further optimize high frequency insertion loss, return loss, and attenuation accuracy characteristics. Refer to the Electrical Specifications section, the Typical Performance Characteristicssection, and the Applications Information section for more details.The ADRF5720 comes in a 24-terminal, 4 mm ? 4 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)
