V3 MA4E2037, MA4E2038 Description and Applications M/A-Com’s MA4E2037 and MA4E2038 single diodes, MA4E2039 anti-parallel pair and MA4E2040 series tee are gallium arsenide beam lead Schottky barrier diodes. These devices are fabricated on OMCVD epitaxial wafers using a process designed for high device uniformity and extremely low parasitics. The high carrier mobility of gallium arsenide results in lower series resistance than a silicon Schottky with equivalent capacitance, resulting in lower noise figure and conversion loss. The diodes are fully passivated with silicon nitride and have an additional layer of a polymer for scratch protection. The protective coatings prevent damage to the junction and the anode air bridge during handling. MA4E2039 Applications The high cut-off frequency of these diodes allows use through millimeter wave frequencies. Typical applications include single and double balanced mixers in PCN transceivers and radios, automotive radar systems and police radar detectors. MA4E2040 The MA4E2039 anti-parallel pair is designed for use in sub harmonically pumped mixers. Close matching of the diode characteristics in high LO suppression at the RF input.

V3 Handling Procedures The following precautions should be observed to avoid damaging these chips: Cleanliness: The chips should be handled in a clean environment. Do not attempt to clean die after installation. Static Sensitivity: Schottky barrier diodes are ESD sensitive and can be damaged by static electricity. Proper ESD techniques should be used when handling these devices. General Handling: The protective polymer coating on the active areas of these die provides scratch protection, particularly for the metal air bridge which contacts the anode. Beam lead devices must, however, must be handled with care since the leads may be easily distorted or broken by the normal pressures exerted when handled by tweezers. A vacuum pencil with a # 27 tip is recommended for picking and placing. Mounting Techniques These devices are designed to be inserted onto hard or soft substrates. Recommended methods of attachment include thermo-compression bonding, parallel- gap welding, solder reflow and conductive epoxy. See application note M541, “ Bonding and Handling Procedures for Chip Diode Devices “ for detailed instructions. 4 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
