The switch features enhanced Al Ga As anodes which are formed using MA’s hetero-junction technology. Al Ga As technology produces a switch with less loss than a device fabricated using conventional Ga As processes. As much as a 0.3 d B 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 anode air-bridges. Off chip bias circuitry is required. APPLICATIONS The high electron mobility of Al Ga As and the low capacitance of the PIN diodes used makes this switch ideal for fast response, high frequency, multi-throw switch designs where the series capacitance in each off-arm will load the input. Al Ga As PIN diode switches are an ideal choice for switching arrays in radar systems, radiometers, test equipment and other multiassembly ponents.
