ADRF5473BCZ - 100MHz to 40GHz 0.5 dB LSB, 6-Bit, Die on Carrier, Silicon Digital Attenuator

Product Overviews

ADRF5473BCZ is a 6-bit digital attenuator with a 31.5 dB attenuation range in 0.5 dB steps manufactured in a silicon process attached on a gallium arsenide (GaAs) carrier substrate. The substrate incorporates the bond pads for chip and wire assembly, and the bottom of the device is metalized and connected to ground. This device operates from 100 MHz to 40 GHz with better than 3.2 dB of insertion loss and excellent attenuation accuracy. The ADRF5473 has an RF input power handling capability of 26 dBm average and 31 dBm peak for all states.
