Title:
POLYPHASE FILTER
Document Type and Number:
WIPO Patent Application WO/2019/202686
Kind Code:
A1
Abstract:
A first resistor (11) to a fourth resistor (14) are connected in series in a ring shape to a first capacitor (21) to a fourth capacitor (24). A first output terminal (41) to a fourth output terminal (44) are connected to the series connection points of the first resistor (11) to the fourth resistor (14) and the first capacitor (21) to the fourth capacitor (24), a first input terminal (31) is connected to the series connection point of the fourth capacitor (24) and the first resistor (11), and a second input terminal (32) is connected to the series connection point of the second capacitor (22) and the third resistor (13). A fifth resistor (15) is connected between the series connection point of the first capacitor (21) and the second resistor (12) and the series connection point of the third capacitor (23) and the fourth resistor (14).
