General Description
LE
The HMC800LP3E 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 2 dB typical and
attenuation accuracy is excellent at ±0.3 dB typical
step error. The attenuator also features a high Input
IP3 of +55 dBm. One TTL/CMOS control input is used
to select the attenuation state and a single Vdd bias of
+5V is required.

[1] Reference this number when ordering complete 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
Hittite upon request.
