Ultra Small SOT26 Package
General Description
The HMC285 & HMC285E are ultra miniature single
balanced mixers in 6 lead plastic surface mount SOT26
packages. This passive MMIC mixer is constructed of
GaAs Schottky diodes and a novel planar transformer
balun on the chip. The RF port is balanced via the
MMIC balun while the LO port is connected directly
to the diodes. The consistent MMIC performance will
improve system operation without the need for exter-
nal components. The SOT26 package is the small-
est footprint available for a complete single-balanced
mixer, 0.118” x 0.118” (3 x 3 mm).
