摘要
研究了四种pin二极管电阻的温度特性。结果表明二极管结面积的大小,也就是二极管结电容的大小,影响着二极管的表面复合和二极管的载流子寿命,决定了二极管的温度性能。器件的钝化方式和几何结构对二极管电阻的温度性能影响不大。结电容为0.1～1.0 pF的微波二极管,具有正的温度系数,约为线性关系,结电容越大,电阻随温度变化越大。研究结果可以用来预测pin二极管开关和衰减器的温度性能,进一步可以应用于电路温度补偿设计。
Four types of temperature performances of pin diode resistance were researched. The results predict that the junction area or say the pin diode capacitance affects the surface recombination and carrier lifetime, and it determines the temperature performance of pin diode. The temperature performance is irrelevant to pin diode geometries and passivation. The resistance-temperature coefficient of pin diode that has low capacitance about 0.1 to 1.0 pF and with different passivations is positive, the relationship of resistance- temperature is a linear approximately. The diode resistance that with large capacitance Cj has higher temperature variation. The results can be used in pin switch and pin attenuator for predict its temperature performance, and can be used in the design of temperature compensation.
