DESCRIPTION
The MA4AGSW5 is an Aluminum-Gallium-Arsenide, single pole, five throw (SP4T), PIN diode switch. The switch features enhanced AlGaAs anodes which are formed using M/A-COM Tech’s patented heterojunction technology. This technology produces a switch with less loss than conventional GaAs processes. As much as a 0.3 dB reduction in insertion loss can be realized at 50GHz. These devices are fabricated on an OMCVD epitaxial wafer using a process designed for high device uniformity and extremely low parasitics. The diodes themselves 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 to the diode junction and anode air-bridges during handling and assembly. Off chip bias circuitry is required.
