| 摘要 |
A transceiver converting communication mode according to the embodiment of the present invention includes a transmitting unit which modulates and amplifies at least one base band transmitting signals with RF band, a duplexer which transmits transmitting signals outputted from the transmitting unit or selects the signal of downlink frequency band and uplink frequency band, transmits it to an antenna, or reflects a receiving signal received from the antenna with the receiving signal of downlink frequency band and uplink frequency band, a receiving unit which demodulates the receiving signals of downlink frequency band and uplink frequency band from the duplexer with at least one base band signal, a first switch which transmits the transmitting signal provided from the transmitting unit in first and second communication modes to a first RF band filter, and a second switch which transmits a first receiving signal transmitted from the second RF filter of the duplexer in the first and third communication mode to the receiving unit. The transmitting unit and the receiving unit include a power amplifier and a low noise amplifier. |
