This single positive control line per bit digital attenuator incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications.
Covering DC to 3.
0 GHz, the insertion loss is less than 2.
0 dB typical.
The attenuator bit values are 0.
5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.
5 dB.
Attenuation accuracy is excellent at ± 0.
5 dB typical step error with an IIP3 of +45 dBm.
Six TTL/CMOS control inputs are used to select each attenuation state.
A single Vdd bias of +5V is required.
