The HMC467LP3 & HMC467LP3E are broadband

2-bit GaAs IC digital attenuators in low cost leadless

surface mount packages. Covering DC to 6.0 GHz, the

insertion loss is less than 0.7 dB typical. The attenuator

bit values are 2 (LSB) and 4 dB for a total attenuation

of 6 dB. Attenuation accuracy is excellent at ± 0.2 dB

typical step error with an IIP3 of +50 dBm. Two control

voltage inputs, toggled between 0 and +5V, are used

to select each attenuation state. A single Vdd bias of

+5V is required.

Evaluation PCB

The circuit board used in the  nal 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.
