Geneal Discription
The H5LP3 & MC539LP3E are broadband
5-bit GaAdigiattenuators in low cost lead-
less surface nt packages. This single positive
control line per bit digital attenuator utilizes an off
p AC ound capacitor for near DC operation,
mat suitable for a wide variety of RF and IF
applications. Covering DC to 4 GHz, the insertion loss
s less than 0.7 dB typical. The attenuator bit values
are 0.25 (LSB), 0.5, 1, 2, and 4 dB for a total attenu-
ation of 7.75 dB. Attenuation accuracy is excellent
at 0.05 dB typical step error. The attenuator also
features a high IIP3 of +50 dBm. Five TTL/CMOS
control inputs are used to select each attenuation
state. A single Vdd bias of +5V is required.

Evaluation PCB
List of Mfor Euation PCB 110078 [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.
