General Description
The HMC285 is an ultra miniature single bal-
anced mixer in an 6 lead plastic surface mount
SOT26 package. This passive MMIC mixer is con-
structed 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 con-
sistent MMIC performance will improve system
operation without the need for external compo-
nents. The SOT26 package is the smallest foot-
print available for a complete single-balanced
mixer, 0.118” x 0.118” (3.0mm x 3.0mm).
