The core circuit is two stages of direct-coupled difference amplifier.
核心电路为两级直接耦合差分放大器。

Then, novel, low-cost and high performance direct-coupled E-plane filters and iris-coupled filters are analysed.
接着设计了新颖的、低成本、高性能直耦E面滤波器和膜片耦合滤波器。

Active inductor loads and direct-coupled technology are employed to increase the gain, broaden the bandwidth, reduce the power dissipation, and keep a tolerable noise performance.
