Solderable GaAs Flip Chip Schottky Diode

 The MADS-001318-1451 anti-parallel pair is a gallium arsenide flip chip Schottky barrier diode. This device is fabricated on OMCVD epitaxial material using a process designed for high device uniformity and extremely low parasitics. This diode is fully passivated with silicon nitride and has an additional layer of polyimide for scratch protection. The protective coating prevents damage to the junction during automated or manual handling. The flip chip configuration is suitable for pick and place insertion. This device can be attached with solder or conductive epoxy. The high cutoff frequency of this diode 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.
