Functional Diagram
General Description
The HMC141 chip is a minature double-balanced
mixer which can be used as an upconverter or
downconverter. The HMC142 is identical to the
HMC141 except that the layout is a mirror image
designed to ease integration into image-reject
mixer modules. Broadband operation and excel-
lent isolations are provided by on-chip baluns,
which require no external components and no DC
bias. The design is similar to the HMC143/144
mixers but without an IF combiner, providing a
broad DC to 6 GHz IF bandwidth. These devices
are much smaller and more reliable than hybrid
diode mixers for VSAT and point-to-point radios.
