Therefore, if we have a way of holding emitter current constant through a transistor, the transistor will work to regulate collector current at a constant value.

于是，只要我们能让晶体管的发射极电流保持恒定，它就能保持发射极电流为恒定值。

For a long time, a common and popular method to solve current convergence problem of microwave power transistor is using emitter ballasting resistor, such as PTC, CTR thermistor, passive devices etc.

长期以来，解决微波功率晶体管的电流集中问题的通用做法是使用发射极镇流电阻，以及PTC, CTR热敏电阻等无源器件。

The ratio of effectual emitter area to base area of a FFJ is 2-3 times greater than a usual transistor and the output power-impedance product is 5-10 times greater.

与通常晶体管相比，FFJ的有效发射极面积对基极面积之比值提高2～3倍，输出功率-阻抗乘积提高5～10倍。
