| 发明名称 | Filtering network in HR-Si silicon technology | ||
| 摘要 | The invention relates to a filtering network in HR-Si silicon technology defined by at least one cut-off frequency and comprising an input terminal for receiving the signal to be filtered and an output terminal for delivering a filtered signal. The network comprises a first ground line connected by its ends to first and second ground points connected directly to the ground plane, a second ground line connected via its ends to third and fourth ground points directly connected to the ground plane, a plurality of L/C resonant elements connected in parallel and linked via one end to one of the two ground lines and via the other end between them, by means of coupling inductors which thus create transmission zeros. Each ground line forming inductive elements via inductances the network comprises capacitive elements in series with at least some of said inductive elements, the value of the capacitive elements being selected so that the resonant frequency of the inductive and capacitive elements in series corresponds to a frequency lying outside of the bandwidth. | ||
