Product Detail

AlGaAs Reflective
The MA4AGSW4 is an Aluminum-Gallium-Arsenide, single pole, four throw (SP4T), PIN diode switch.The switch features enhanced AlGaAs anodes whichare formed using MACOM’s patented heterojunctiontechnology. This technology produces aswitch with less loss than conventional GaAs processes.As much as a 0.3 dB reduction in insertionloss can be realized at 50GHz. These devices arefabricated on an OMCVD epitaxial wafer using aprocess designed for high device uniformity andextremely low parasitics. The diodes themselvesexhibit low series resistance, low capacitance, andfast switching speed. They are fully passivated withsilicon nitride and have an additional polymer layerfor scratch protection. The protective coatingprevents damage to the diode junction and anodeair-bridges during handling and assembly. Off chipbias circuitry is required.The high electron mobility of AlGaAs and the lowcapacitance of the PIN diodes makes this switchideal for fast switching, high frequency, multi-throwswitch designs. These AlGaAs PIN switches are usein switching arrays for radar systems, radiometers,test equipment and other multi-assembly components.
