AlGaAs SP4T Reflective Switch

 The MASW-011087 is a high power, symmetrical SP4T switch. This broadband, reflective switch was developed for Ka-Band applications that require up to 30 dBm (1 W) power handling while maintaining low insertion loss, high isolation, and fast switching speed. These switches are used in switching arrays of radars systems, radiometers, test equipment, Point-to-Point communications systems and other high frequency applications. The SP4T MMIC utilizes MACOM’s proven AlGaAs PIN diode technology. The switch is fully passivated with silicon nitride and has an added polymer layer for scratch protection. The protective coating prevents damage to the junction and the air-bridges during handling and assembly. The die has backside metallization to facilitate an epoxy die attach process.
