Functional Diagram
General Description
The HMC472LP4 & HMC472LP4E are broadband
6-bit GaAs IC digital attenuators in low cost leadless
surface mount packages. This single positive control
line per bit digital attenuator incorporates off chip AC
ground capacitors for near DC operation, making it
suitable for a wide variety of RF and IF applications.
Covering DC to 3.8 GHz, the insertion loss is less
than 2.0 dB typical. The attenuator bit values are 0.5
(LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of
31.5 dB. Attenuation accuracy is excellent at 0.25 dB
typical step error with an IIP3 of +45 dBm. Six TTL/
CMOS control inputs are used to select each attenua-
tion state. A single Vdd bias of +5V is required.

Evaluation PCB
List of Materials for Evaluation PCB 107010 [1]
The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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.
