摘要

提出了微波功率放大器/组合器的动态原理，并给出了小输入电平下的增益表达式。结果表明，当两个组合放大器的谐振频差/spl δ //sub 21/增大时，增益-带宽积(GBP)增大，因此通过控制/spl δ //sub 21/，可以获得比GBP恒定1.>的单放大器更宽的带宽

Dynamic behavior of a microwave power amplifier/combiner

A dynamic theory of a microwave power amplifier/combiner is presented and a gain expression is obtained at small input signal level. It is found that the gain-bandwidth product (GBP) will increase when the resonant frequency difference /spl delta//sub 21/ of these two combined amplifiers increases, so that by controlling /spl delta//sub 21/ one can obtain a broader bandwidth than the single amplifier whose GBP is constant 1.<>
