Functional Diagram
General Description
The HMc207as8 & HMc207as8e are miniature dou-
ble-balanced mixers in 8 lead plastic surface mount
Small Outline IC (SOIC) packages. This passive
MMIC mixer is constructed of GaAs Schottky diodes
and novel planar transformer baluns on the chip. The
device can be used as an upconverter, downconverter,
biphase modulator (de)modulator, or phase compara-
tor. The consistent MMIC performance will improve
system operation and assure regulatory compliance.
The high LO suppression of 45 to 50 dB yields excel-
lent carrier suppression for modulator applications.

No connection required. These pins may be connected to RF/
DC ground without affecting performance.
This pin is DC coupled. For applications not requiring opera-
tion to DC, this port should be DC blocked externally using a
series capacitor whose value has been chosen to pass the
necessary IF frequency range. For operation to DC, this pin
must not source or sink more than 10 mA of current or part
non-function and possible part failure will result.
