AlGaAs Beamlead PIN Diode MA4AGBLP912 Rev. V6 Features Low Series Resistance Low Capacitance 5 Nanosecond Switching Speed Can be Driven by a Buffered +5 V TTL Topside Silicon Nitride Passivation Polyimide Scratch Protection RoHS Compliant Applications Aerospace & Defense ISM Bottom Description The MA4AGBLP912 is an Aluminum-Gallium- Arsenide anode enhanced, beam lead PIN diode. AlGaAs anodes, which utilize MACOMs patented hetero-junction technology, produce less diode On resistance than conventional GaAs or silicon Outline devices. This device is fabricated in a OMCVD system using a process optimized for high device uniformity and extremely low parasitics. The result is a diode with low series resistance, 4 , low capacitance, 28 fF, and an extremely fast switching speed of 5nS. It is fully passivated with silicon nitride and has an additional polymer coating for scratch protection. The protective coating prevents damage to the junction and the anode air bridges during handling and assembly. The ultra low capacitance of the MA4AGBLP912 device makes it ideally suited for use up to 40 GHz when used in a shunt configuration. The low RC product and low profile of the beamlead PIN diode allows for use in microwave switch designs, where low insertion loss and high isolation are required. The operating bias conditions of +10 mA for the low loss state, and 0 V, for the isolation state permits the Outline Dimensions use of a simple +5 V TTL gate driver. AlGaAs, beamlead diodes, can be used in switching arrays INCHES MM on radar systems, high speed ECM circuits, optical Dim. switching networks, instrumentation, and other Min. Max. Min.

Parameter Absolute Maximum Cleanliness Reverse Voltage -50 V These devices should be handled in a clean environment. Forward DC Current 40 mA Static Sensitivity C.W. Incident Power 23 dBm Aluminum Gallium Arsenide PIN diodes are Class 0, HBM, ESD sensitive and can be damaged by static Junction Temperature +175C electricity. Proper ESD techniques should be used Operating Temperature -65C to +125C when handling these devices. Storage Temperature -65C to +150C General Handling These devices have a polymer layer which provides Mounting Temperature +235C for 10 seconds scratch protection for the junction area and the anode air bridge. Beam lead devices must, however, be handled with extreme care since the leads may easily be distorted or broken by the normal pressures exerted when handled with tweezers. A vacuum pencil with a 27 tip is recommended for picking and placing. Attachment These devices were designed to be inserted onto hard or soft substrates. Recommended methods of attachment include thermo-compression bonding, parallel-gap welding and electrically conductive silver epoxy. 22 2 MACOM Technology Solutions Inc.
