MIXERS - DOUBLE-BALANCED - CHIP
Functional Diagram
General Description
The HMC143 chip is a minature double-balanced
mixer which can be used as an upconverter or down-
converter. The chip utilizes a standard 1μm GaAs
MESFET process. The HMC144 is identical to the
HMC143 except that the layout is a mirror image
designed to ease integration into image-reject
mixer modules. Broadband operation and excellent
isolations are provided by on-chip baluns, which
require no external components 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.
