Using Agilent Temperature Compensated Thermistor Mounts With TEGAM Type IV Power Meters

USING AGILENT TEMPERATURE COMPENSATED THERMISTOR MOUNTS WITH TEGAM TYPE IV POWERMETERS

Thermistor-based RF power sensors are known by many names including thermistor mounts, thermistor sensors and bolometers. Thermistor sensors such as the Agilent (HP) 478A and TEGAM F1109 are dual thermistor based. In dual thermistor sensors, a pair of thermistor beads is used to detect RF power. When RF power is applied to the thermistor pair, their resistance decreases. This decrease can be measured and the amount

of RF power applied can be determined.
