HIGH FREQUENCY CIRCUIT, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/157725
Kind Code:
A1
Abstract:
A high frequency circuit (1) comprises a carrier amplifier (21) capable of amplifying high frequency signals in a band A, a carrier amplifier (22) capable of amplifying high frequency signals in a band B, peak amplifiers (23 and 24) capable of amplifying high frequency signals in the band A and high frequency signals in the band B, a transformer (30) having an input side coil (301) and an output side coil (302), and phase shifting lines (51 and 52), wherein: an output terminal of the peak amplifier (23) is connected to one end of the input side coil (301); an output terminal of the peak amplifier (24) is connected to another end of the input side coil (301); an output terminal of the carrier amplifier (21) is connected to one end of the phase shifting line (51); an output terminal of the carrier amplifier (22) is connected to one end of the phase shifting line (52); another end of the phase shifting line (51) is connected to one end of the output side coil (302); and another end of the phase shifting line (52) is connected to another end of the output side coil (302).
