Functional Diagram
General Description
The HMC472ALP4E 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 suit-
able 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 +54 dBm. Six TTL/
CMOS control inputs are used to select each attenua-
tion state. A single Vdd bias of +5V is required.

List of Materials for Evaluation PCB 107010 - HMC472ALP4 [1]
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, upon request.
