The P/N 9D8-420822T and P/N 13D12-4808221 are based on the standard design of the SP8T and the SP12T internally terminated switches. Access to the termination port, via SMA connectors, allows for the utilization of the remotely mounted high power 50 Ω termination, dramatically increasing the power handling of these units. The 13D12-480822T performs up to 18 GHz; the 9D8-420822T performs up to 26 GHz. These Ethernet (802.3) based switch matrices can be easily accessed from anywhere in the world via TCP/IP protocols on 10BaseT networks. The switches can also be controlled using the CANBus interface. Each unit is supplied with the contact-less indicator circuitry monitoring the movement of the RF contact actuators using photo-sensors.
