HMC144
The HMC143 chip is a miniature doublebalanced mixer which can be used as an
upconverter or downconverter. 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 mixer designs for VSAT and point-topoint radios.
