技術摘要 / Our Technology:
一種整合有帶通濾波功能之單刀雙擲切換器包含四個串聯之四分之一波長傳輸線、五個並聯之共振器及四個分別與該五個共振器中之四個共振器並聯之電晶體。當該四個電晶體中之二個電晶體係導通的而另二個電晶體係不導通的時,該單刀雙擲切換器可等效為一種第三級四分之一波長短路殘帶帶通濾波器。
A single-pole-double-throw switch is provided, which is configured to be integrated with a bandpass filtering function and includes four quarter-wavelength transmission lines connected in series, five resonators connected in parallel to each other, and four transistors connected in parallel to four of the five resonators. When two of the four transistors are turned on and the others are turned off, the single-pole-double-throw switch is equivalent to a third-order quarter-wavelength short-circuited stub bandpass filter.
