SPDT AlGaAs PIN Diode Switch MA4AGSW2 Rev. V8 Features Ultra Broad Bandwidth: 50 MHz to 50 GHz Functional Bandwidth: 50 MHz to 70 GHz Insertion Loss: 0.7 dB Isolation: 33 dB 50 GHz Low Current Consumption: -10 mA for Low Loss State +10 mA for Isolation State MACOMs Unique AlGaAs Hetero-Junction Anode Technology Silicon Nitride Passivation Polymer Scratch Protection RoHS Compliant Applications Yellow areas indicate bond pads Aerospace & Defense ISM Description The MA4AGSW2 is an Aluminum-Gallium-Arsenide, single pole, double throw (SPDT), PIN diode switch. The switch features enhanced AlGaAs anodes which are formed using MACOMs hetero-junction technology. AlGaAs technology produces a switch with less loss than a device fabricated using conventional GaAs processes. As much as a 0.3 dB reduction in insertion loss can be realized at 50 GHz. This device is fabricated on an OMCVD epitaxial wafer using a process designed for high device uniformity and extremely low parasitics. The diodes within the chip exhibit low series resistance, low capacitance, and fast switching speed. They are fully passivated with silicon nitride and have an additional polymer layer for scratch protection. The protective coating prevents damage during handling and assembly to the diode junction and the chip Ordering Information anode air-bridges. Off chip bias circuitry is required. Part Number Package The high electron mobility of AlGaAs and the low capacitance of the PIN diodes used makes this MA4AGSW2 waffle pack switch ideal for fast response, high frequency, multi-throw switch designs. AlGaAs PIN diode MASW-000552-13210G Gel Pack switches are an ideal choice for switching arrays in radar systems, radiometers, test equipment and other multi-assembly components. 11 1 MACOM Technology Solutions Inc.
