Ducommun has introduced multi-throw coaxial switches that can be controlled and powered using Power over Ethernet (PoE). This option is available with a range of Ducommun products from SP3T to 6T, covering DC to 40 GHz. Since the switch is powered through the Ethernet connection, no external power supply is needed. The PoE interface provides a unique, configurable IP address, and the switch can be controlled remotely from a Windows PC (32 or 64 bit) as well as Android and iOS smartphone apps.
PoE control is useful in a wide variety of applications, including test equipment, control systems and general lab work. Several switches can be configured into a switch matrix using a single Ethernet hub.
Up to 10 GHz, the bidirectional switch has less than 0.4 dB insertion loss, greater than 60 dB isolation, and better than 1.4:1 VSWR. Switching time, including the command, is within 100 msec. Control functionality is available with failsafe and normally open modes. The operating temperature range is -35° to +85°C, and the operating life is greater than 1,000,000 throws. The cylindrical design is 1.5 inch in diameter and 7 inches tall, with a standard RJ45 connection for the PoE interface.
