Product Details
The ADRF5474 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.
The ADRF5474 requires a dual-supply voltage of +3.3 V and −3.3 V. The device features parallel mode control, and complementary metal-oxide semiconductor (CMOS)-/low voltage transistor to transistor logic (LVTTL)-compatible controls.
The ADRF5474 is designed to match a characteristic impedance of 50 Ω.
