Effect of temperature on power response of PIN diode limiter
According to the relationship between the parameters of PIN diode and temperature,power response characteristics of PIN diode limiter at different temperatures are simulated with a limiter circuit model which is based on the base area ambipolar carrier transport equation of PIN diode in Pspice.The results show that the power loss in the limiter is increased when the temperature increass.A temperature control system was employed in the experiment.The experimental results agree with the simulation results.After one thermal shock,it is observed that the limiting capacity of the limiter is weakened.
