General Description
The HMC801LP3E is a broadband bidirectional 1-bit
GaAs IC digital attenuator in a low cost leadless sur-
face mount package. This single positive control line
digital attenuator utilizes off chip AC ground capaci-
tors for near DC operation, making it suitable for a
wide variety of RF and IF applications. Covering DC
to 10 GHz, the insertion loss is less than 2 dB typical
and attenuation accuracy is excellent at ±0.4 dB typi-
cal step error. The attenuator also features a high IIP3
of +53 dBm. One TTL/CMOS control input is used to
select the attenuation state and a single Vdd bias of
+5V is required.
