Ka-Band high power terminated SPDT PIN switch

April 03, 2017 // By Julien Happich
Macom's MASW-011094 is a high power SPDT PIN switch with 50 Ohm terminated RF ports.

This broadband, high linearity, SPDT switch was developed for Ka–Band applications that require up to 40-W CW power handling at an environmental temperature of +85°C. It features over 26 dB of isolation and exhibits a low 0.6 dB loss over the 28 to 34 GHz range while switching under 65ns.

The SPDT MMIC uses 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. These switches are suitable for satellite and Point-to-Point communications systems, radar systems, radiometers, test and instrumentation equipment and other high frequency applications
