Functional Diagram
General Description
The HMC203 chip is a miniature double-balanced
mixer which can be used as an upconverter or
downconverter. Excellent isolations are provided
by on-chip baluns, which require no external com-
ponents and no DC bias. The mixer chip can
be integrated directly into MMIC hybrid applica-
tions. Unless otherwise stated, all data was mea-
sured with the mixer mounted in a MMIC test
鏗亁ture. The MMIC was connected to thin鏗乴m 50
ohm transmission lines with 1 mil diameter wire-
bonds of <10 mils in length.
