General Description
The HMC207S8 is a miniature double-balanced mixer in an 8 lead plastic surface
mount Small Outline IC (SOIC) package.
This passive MMIC mixer is constructed of
GaAs Schottky diodes and novel planar
transformer baluns on the chip. The device
can be used as a up, or downconverter, biphase modulator (de)modulator or phase
comparator for 900, 1500, or 1900 MHz
applications. It is especially suited for miniature base stations, cable modems, and
portable wireless applications because of
its high dynamic input signal range, and
zero DC bias requirement. The consistent
MMIC performance will improve system operation and assure regulatory compliance.
The high LO suppression of 45 to 50 dB
yields excellent carrier suppression for
modulator applications.
Guaranteed Perf ormance As a Function of LO Drive , -40 to +85 deg C
