Functional Diagram
General Description
The HMC143 chip is a minature double-balanced
mixer which can be used as an upconverter or
downconverter. The chip utilizes a standard 1um
GaAs MESFET process. The HMC144 is iden-
tical to the HMC143 except that the layout is a
mirror image designed to ease integration into
image-reject mixer modules. Broadband oper-
ation and excellent isolations are provided by
on-chip baluns, which require no external compo-
nents and no DC bias. The design is similar to
the HMC141/142 mixers but with an IF combiner
in a double-balanced design, providing improved
RF/IF isolation. These devices are much smaller
and more reliable replacements to hybrid diode
mixers.
