Inductive Output Tubes (IOT)

The IOTD 130 IOT tube is designed for high-power, continuous operation at up to 30 kW average output power in 8VSB or COFDM modulation schemes.  It is a plug-in compatible replacement for all IOTs similar to the D2100/8505 and will fit in all L3 trolley systems.  A getter ion pump is part of the tube assembly and requires 3 to 4 kV with respect to the heater for normal operation.

The IOTD 130D IOT is designed as a direct replacement for the e2v D2130.  Minor modifications to the cooling hoses are required and all hardware necessary for the tube replacement is included with the product when it is shipped.  The modifications can be installed in less than 1 hour using simple hand tools.
