Overview

APPLICATION NOTE APN2014: 6 Bit 63 dB RF Digital Attenuator Solution 500–2000 MHz High dynamic range systems often require an attenuator with a very wide attenuation range.
It is possible to achieve 63 dB attenuation range by cascading two low cost digital attenuators, AA101-80 and AA104-73.
It is effectively impossible to achieve such high attenuation range with a single package device.
AA101-80 is a 5-bit attenuator with a 1 dB least significant bit (LSB).
Full-scale attenuation for this attenuator is 31 dB.
AA104-73 is a 1-bit digital attenuator that produces 32 dB attenuation.
When these two attenuators are cascaded on a standard FR4 printed circuit board, 63 dB total attenuation range ...
