General Description
The HMC294 chip is a miniature passive
double-balanced mixer which can be used
as an upconverter or downconverter from 25
- 40 GHz in a small chip area of 1.70 mm2.
Excellent isolations are provided by on-chip
baluns, which require no external components and no DC bias. The mixer chip is
designed to be used in Local Multi- Point
Distribution Systems (LMDS), microwave
point to point radios, and SATCOM applications. All data is measured with the chip in
a 50 ohm test fixure connected via 0.076 mm
(3 mil) gold ribbon of minimal length <0.31
mm (<12 mils).
Guaranteed Perf ormance With LO Drive of +14 dBm, -55 to +85 deg C
