MA4Exxxx Series
GaAs Flip Chip Schottky Barrier Diodes
Features
Low Series Resistance Low Capacitance High Cutoff Frequency Silicon Nitride Passivation Polyimide Scratch Protection Designed for Easy Circuit Insertion
Description and Applications
The MA4E1317 single, MA4E1318 anti-parallel 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.
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.
