Title:
HIGH FREQUENCY CIRCUIT AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/120073
Kind Code:
A1
Abstract:
This high-frequency circuit (1) can simultaneously transmit signals of a band A and signals of a band B, the circuit comprising: antenna terminals (110 and 120); a power amplifier (21) corresponding to a first power class; a power amplifier (22) corresponding to a second power class the transmitting power of which is greater than that of the first power class; a switch (31) which has a common terminal (31a) and terminals (31b and 31c), the common terminal (31a) being connected to the antenna terminal (110); a filter (11) which has an input terminal connected to the power amplifier (21) and an output terminal connected to the terminal (31b), and has a first pass band including at least a portion of the band A; a filter (12) which has an input terminal connected to the power amplifier (22) and an output terminal connected to the antenna terminal (120) without the switch interposed therebetween, and has a second pass band including at least a portion of the band B; and a filter (13) which is connected to the terminal (31c) and has a third pass band.
