Electrical Specications, TA = +25° C, With Vdd = +5V & Vctl = 0/+5V
The HMC802LP3E is ideal for both RF
and IF applications:
• Test Equipment and Sensors
• ISM, MMDS, WLAN, WiMAX, WiBro
• Microwave Radio & VSAT
• Cellular Infrastructure

The HMC802LP3E is a broadband bidirectional 1-bit
GaAs IC digital attenuator in a low cost leadless
surface mount package. This single positive control
line digital attenuator utilizes off chip AC ground
capacitors 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 typical. 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 Hit-
tite upon request.
