Functional Diagram
General Description
The HMC218MS8 is an ultra miniature double-
balanced mixer in an 8 lead plastic surface mount
package (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 (de)modulator, or phase comparator.
The consistent MMIC performance will improve
system operation and assure regulatory compli-
ance.
