Functional Diagram
General Description
The HMC218MS8 & HMC218MS8E are ultra miniature
double-balanced mixers in 8 lead plastic surface
mount packages (MSOP). 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, bi-
phase modulator / demodulator, or phase comparator.
The low conversion loss, high isolation and wide IF
bandwidth make this mixer ideal for a variety of Rx and
Tx frequency plans.
