General Description
The HMC539ALP3/539ALP3E is
a
broadband
5-bit GaAs IC digital attenuator in a low cost lead-
less surface mount package. This single positive
control line per bit digital attenuator utilizes an off
chip AC ground capacitor for near DC operation,
making it suitable for a wide variety of RF and IF
applications. Covering DC to 4 GHz, the inser-
tion loss is less than 0.7 dB typical. The attenuator
bit values are 0.25 (LSB), 0.5, 1, 2, and 4 dB for a
total attenuation of 7.75 dB. Attenuation accuracy is
excellent at 0.05 dB typical step error. The attenu-
ator also features a high IIP3 of +62 dBm. Five TTL/
CMOS control inputs are used to select each attenua-
tion state. A single Vdd bias of +3V to +5V is required.

Evaluation PCB
List of Materials for Evaluation PCB EV1HC539ALP3 [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 Inc upon request.
