Description and Applications
M/A-COM's MA4E1317 single, MA4E1318 anti-
parallel
pair,
MA4E1319-1
reverse
tee,
MA4E1319-2 series tee and MA4E2160 uncon-
nected 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 addi-
tional 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.
The MA4E1318 anti-parallel pair is designed for
use in sub harmonically pumped mixers. Close
matching of the diode characteristics results in
high LO suppression at the RF input.
