中文摘要:在無線通訊系統中,為了在不同的通道中分別傳輸不同頻率的等功率訊號,可以在雙工器的輸出埠分別串接不同頻率的威爾京生功率分配器,但其中的雙工器往往同時需要匹配電路與濾波器,為了可以達到雙工等功率分配且不需要濾波器的目的,本計畫提出四種雙工功率分配器,若需增加選擇度,可以使用一雙頻濾波器串接於擬提出的各雙工功率分配器之輸入埠,相較於在雙工器的輸出埠分別串接不同頻率的威爾京生功率分配器,擬提出的雙工功率分配器可以視選擇度的需要而決定是否需要加濾波器,換句話說,相較於在傳統雙工器的輸出埠分別串接不同頻率的威爾京生功率分配器,提之電路具有較高的設計彈性度。
英文摘要:In wireless communication system, output ports of a diplexer can cascade different frequency Wilkinson power dividers for transmitting different frequency equal power signals in different paths, wherein matching circuits and two different frequency filters are usually needed simultaneously for a diplexer design. To achieve diplexing power division without costing filters, four new microstrip diplexing power dividers are proposed in this program. A dual-band filter can be cascaded at input port of each proposed diplexing power divider if the selectivity is required to be increased. Compared with a conventional diplexer by cascading different frequency Wilkinson power dividers at its output ports, each of the proposed diplexing power dividers can depend on the selectivity requirement whether it adds filter or not. In other words, the proposed each circuit demonstrates a better design flexibility than a conventional diplexer by cascading different frequency Wilkinson power dividers at its output ports.
