  • Power synthesis circuit for radio frequency power amplifier
    Patent number: 8872599
    Abstract: A power synthesis circuit for a radio frequency (RF) power amplifier comprises a first matching network and a second matching network, which are connected with two-band signal output ports of the RF power amplifier respectively, and signal coupling circuits which are connected with two-band signal receiving ports respectively. The first matching network and the second matching network are connected with an antenna circuit via a duplexer, and are grounded via an inductor and a switch element which is connected in parallel to the inductor respectively. The leakage of signal among different channels is prevented. The transmission quality of the RF signal is improved. The cost of the power amplifier is reduced and the structure of the power amplifier is simplified.
