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.

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Analog Devices Inc. upon request.
