General Description
The HMC467LP3 & HMC467LP3E are broadband
2-bit GaAs IC digital attenuators in low cost leadless
surface mount packagesꢀ Covering DC to 6ꢀ0 GHz, the
insertion loss is less than 0ꢀ7 dB typicalꢀ The attenuator
bit values are 2 (LSB) and 4 dB for a total attenuation
of 6 dBꢀ Attenuation accuracy is excellent at 0ꢀ2 dB
typical step error with an IIP3 of +50 dBmꢀ Two control
voltage inputs, toggled between 0 and +5V, are used
to select each attenuation stateꢀ A single Vdd bias of
+5V is requiredꢀ

Evaluation PCB
List of Materials for Evaluation PCB 107008 [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.
