Abstract
A multiband radio frequency transmitter of a transceiver in which a receiving band is varied, includes a transmitting circuit, a receiving band-rejection filter, a power amplifying circuit, and an impedance compensating circuit. The transmitting circuit is configured to generate a transmission signal. The receiving band-rejection filter is configured to vary a rejection band in response to a variation of the receiving band, and reject the receiving band from the transmission signal provided from the transmitting circuit. The power amplifying circuit is configured to amplify the transmission signal that passes through the receiving band-rejection filter. The impedance compensating circuit is configured to compensate for impedance mismatch due to the variation of the rejection band of the receiving band-rejection filter.
