Abstract :
RF bolometer thermistor is studied for a wide frequency range. A novel equivalent electrical model is presented to show the non-linear behavior of the bolometer thermistor for different polarization DC-currents. This model has been used as “detector section” of a bolometer RF-power sensor and the its “efficiency η” evaluated by the simple and quick “3-Γ i.e. Impedance Method”.
