High-frequency circuit apparatus and communication apparatus using the same |
摘要 |
A high-frequency circuit has a duplexer and a filter. The duplexer performs wave separation of send and received signals as input thereto. The filter filters the input send signal. When the send and received signals of the first modulation method are input, the send signal and the received signal of the first modulation method are wave-separated and output by the duplexer. When the received signal of the first modulation method is input, the send signal and the received signal of the first modulation method are wave-separated and output by the duplexer, and the send signal of the second modulation method is filtered by the filter.
