The HMC147S8 is a miniature double-bal-
anced mixer in a plastic surface mount Small-
Outline IC (SOIC) package. The device can
be used as an upconverter or downconverter
and is especially suitable for base station
and portable wireless applications because
of its small size and zero DC bias require-
ment. The mixer provides exceptional isola-
tion and intermodulation performance for
application in high signal density environ-
ments. This device can also be used as a
biphase modulator/demodulator, or Phase
Comparator. See the smaller MSOP8 Pack-
aged Equivalent mixer HMC175MS8.

Evaluation Circuit Board
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 should be connected directly to the ground plane
similar to that shown above. The evaluation circuit board as shown is available from Hittite upon request.
