General Description
The HMC802ALP3E 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 capac-
itors 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 3 dB typical
and attenuation accuracy is excellent at ±0.6 dB typ-
ical. The attenuator also features a high IIP3 of +55
dBm. One TTL/CMOS control input is used to select
the attenuation state and a single Vdd bias of +5V is
required.
