They are fully passivated with silicon nitride and have an additional layer of a polymer for scratch protection. The protective coatings prevent damage to the junction and the anode airbridge during handling. The 25 fF capacitance of the MA4AGP907 is useable for mmwave switch and switched phase shifter applications. This diode is designed for use in pulsed or CW applications, where single digit nS switching speed is required. For surface mount assembly, the low capacitance of the MA4AGP907 makes it ideal for use in microwave multithrow switch assemblies, where the series capacitance of each "off" port adversely loads the input and affects VSWR.
