Ultra Broad Bandwidth: Functional bandwidth Insertion Loss, Isolation Current consumption: Loss State Isolation M/A-COM's unique patent pending AlGaAs hetero-junction anode technology Silicon Nitride Passivation Polymide Scratch protection
MA4AGSW2 Layout
Description
M/A-COM's MA4AGSW2 Aluminum-Gallium-Arsenide anode enhanced, SP2T diode switch. AlGaAs anodes, which utilize M/A-COM's patent pending hetero-junction technology, which produce less loss than conventional GaAs processes, much reduction insertion loss GHz. These devices fabricated OMCVD epitaxial wafer using process designed high device uniformity extremely parasitics. diodes themselves exhibit series resistance, capacitance, fast switching speed. They fully passivated with silicon nitride have additional layer polymer scratch protection. protective coating prevents damage junction anode airbridges during handling. Off-chip bias circuitry required allows maximum design flexibility.

AlGaAs SP2T Diode Switch Assembly Considerations
following precautions should observed avoid damaging these chips.
MA4AGSW2
1.00
Solder Attachment
attach bonding methods should compatible with gold metal. Solder which does scavange gold, such 80Au/20Sn Sn62/Pb36/Ag2 recommended. expose temperature greater than more than seconds.
Cleanliness
These chips should handled clean environment. attempt clean after installation.
Electrically Conductive Epoxy Attachment
Assembly preheated approximately controlled thickness approximately mils best electrical thermal conductivity. Cure epoxy manufacturer's schedule. extended cure times, temperatures should kept below
Electro-Static Sensitivity
These Devices considered Class1. Proper techniques should used when handling these devices.
General Handling
protective polymer coating active areas these provides scratch impact protection, particularly metal airbridge which contacts diode's anode. should primarily handled with vacuum pickups, alternatively with plastic tweezers.
Ribbon/Wire Bonding
Wedge thermocompression bonding ball bonding used attach ribbons wires bonding pads. Gold ribbons should ports lowest inductance best microwave performance.
Mounting Techniques
These AlGaAs devices designed mounted with electrically conductive silver epoxy with lower temperature solder perform, which rich content.
