General Description
The HMC656LP2E / 657LP2E / 658LP2E are a
line of wideband fixed value SMT 50 Ohm matched
attenuators which offer relative attenuation levels
of 10, 15 and 20 dB respectively. These passive
attenuators are ideal for military, test equipment, and
other wideband applications where extremely flat
attenuation, and excellent VSWR vs. frequency are
required.
These wideband attenuators handle up to +25 dBm
of input power, and are compatible with high volume
surface mount manufacturing techniques.

The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have 50
ohm impedance and the package ground leads and
exposed paddle should be connected directly to the
ground plane similar to that shown above. The eval-
uation circuit board shown above is available from
Hittite Microwave Corporation upon request.
