APN2014 Datasheet (Skyworks) - 6 Bit 63 dB RF Digital Attenuator

APN2014, 6 Bit 63 dB RF Digital Attenuator

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).
