Title:
MULTIPLEXER
Document Type and Number:
WIPO Patent Application WO/2023/090238
Kind Code:
A1
Abstract:
This multiplexer (1) comprises a shared terminal (91), an inductor (40) having one end connected to the shared terminal (91), a filter (10) connected to the other end of the inductor (40), and filters (20 and 30) connected to the shared terminal (91) without passing through the inductor (40). The impedance in the passband when the filter (10) to which the inductor (40) is connected is viewed from the shared terminal (91) while the filters (20 and 30) are not connected to the shared terminal (91) exhibits inductivity. The average value of the conductance in the passband when the filter (20) positioned on the low frequency side of the filters (20 and 30) is viewed from the shared terminal (91) while the filters (10 and 30) are not connected to the shared terminal (91) is larger than the average value of the conductance in the passband when the filter (30) alone is viewed from the shared terminal (91).
