Title:
HIGH-FREQUENCY CIRCUIT AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/264862
Kind Code:
A1
Abstract:
This high-frequency circuit (1) is capable of simultaneously transmitting a band-A signal and a band-B signal, where, when f1 represents the frequency of a first uplink operation band of the band A and f2 represents a second uplink operation band of the band B, then (2 × f2 - f1) overlaps a second downlink operation band of the band B. The high-frequency circuit (1) comprises antenna connection terminals (110, 120, 130) connected to different antennas, a filter (21) connected to the antenna connection terminal (110) and having a passband that includes the first uplink operation band, a filter (34) connected to the antenna terminal (120) and having a passband that includes the second uplink operation band, and a filter (43) connected to the antenna terminal (130) and having a passband that includes the second downlink operation band.
