Power efficient transmitter with high dynamic range |
摘要 |
One embodiment of the present invention relates to a method for transistor matching. The power transmitter comprises a first, second, and third amplification path. The paths are selectively activated and deactivated to output a received signal with high efficiency and linearity. The first amplification path is configured to receive a first signal and output a first amplified signal to a first port of a output power combiner when activated and provide an impedance that results in a high reflection factor when deactivated. The second amplification path is configured to receive a second signal with 90° phase shift with respect to the first signal and output a second amplified signal to a second port of the combiner when activated and provide an impedance that results in a high reflection factor when deactivated. The third amplification path is configured to receive a third signal and output a third amplified signal to a third port of the output power combiner when activated and provide an impedance that results in an impedance that matches the output impedance when deactivated. |
