MACOM's MA4E1317 single, MA4E1318 antiparallel
pair, MA4E1319-1 reverse tee,MA4E1319-2 series tee and MA4E2160 unconnected anti-parallel pair are gallium arsenide flip
chip Schottky barrier diodes. These devices are
fabricated on OMCVD epitaxial wafers using a
process designed for high device uniformity and
extremely low parasitics. The diodes are fully
passivated with silicon nitride and have an additional
layer of polyimide for scratch protection.
The protective coatings prevent damage to the
junction during automated or manual handling.
The flip chip configuration is suitable for pick
and place insertion. The high cutoff frequency
of these diodes allows use through millimeter
wave frequencies. Typical applications include
single and double balanced mixers in PCN
transceivers and radios, police radar detectors,
and automotive radar detectors. The devices
can be used through 80 GHz.
