General Description
The HMC541LP3 & HMC541LP3E are broadband
1-bit GaAs IC digital attenuators in low cost lead-
less surface mount packages. This single posi-
tive 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 5.0 GHz, the insertion
loss is less than 1.0 dB typical. Attenuation accuracy is
excellent at 0.2 dB typical step error. The attenuator
also features a high IIP3 of +50 dBm. One TTL/CMOS
control input is used to select the attenuation state. A
single Vdd bias of +5V is required.

List of Material for Evaluation PCB 111317 [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 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 avail-
able from Hittite upon request.
