DBL-BAL Mixer Chip, 5 - 20 GHz

The HMC143 chip is a miniature double-balanced mixer which can be used as an upconverter or downconverter. The chip utilizes a standard 1μm GaAs MESFET process. The HMC143 is identical to the HMC144 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 / HMC142 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.
