General Description
The HMC218AMS8E is an ultra miniature double-bal-
anced mixer in an 8 lead plastic surface mount pack-
age (MSOP). This passive MMIC mixer is constructed
of GaAs Schottky diodes and novel planar trans-
former baluns on the chip. The device can be used as
an upconverter, downconverter, biphase modulator /
demodulator, or phase comparator. The low conver-
sion loss, high isolation and wide IF bandwidth make
this mixer ideal for a variety of Rx and Tx frequency
plans.
