摘要
针对两种不同耦合电容器在不同情况下能否实现备用进行探讨,提出了当耦合电容器电容量增大时,结合滤过器的通频带也增大,且通道工作频率较高的情况下,使用电容量更大的耦合电容器来做为备用耦合电容器的可行性是很高的。反之,在通道工作频率较低的情况下,使用电容量较小的耦合电容器做为备用耦合电容器的可行性较差。
As for different capacity coupling capacitors＇ spare characteristic for each other, it is feasible to use coupling capacitor with bigger capacity as spare one when pass band of filter increase and frequency is high. It is not suitable to use coupling capacitor with small capacity.
