ADRF5474BCZ - 10MHz to 60GHz, 2dB LSB, 4-Bit, Die on Carrier, Silicon Digital Attenuator

Product Overviews

ADRF5474BCZ is a 4-bit digital attenuator with 22 dB attenuation control range in 2 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 10 MHz to 60 GHz with better than 2.7 dB of insertion loss and excellent attenuation accuracy at 55 GHz. The ADRF5474 has a RF input power handling capability of 23 dBm average and 24 dBm peak for all states.
