TD-SCDMA/GSM双模手机射频功率放大器模块
摘要：
本发明涉及一种TD-SCDMA/GSM双模手机射频功率放大器模块，它包括用于接收并处理TD输入信号的TD-SCDMA功率放大芯片、用于接收并处理GSM输入信号的GSM功率放大芯片、与所述的TD-SCDMA功率放大芯片和GSM功率放大芯片相电连接用于交替地控制所述的TD-SCDMA功率放大芯片和GSM功率放大芯片的控制芯片，且所述的TD-SCDMA功率放大芯片、GSM功率放大芯片、控制芯片整合为一个模块，从而取代了原TD-SCDMA功放与GSM功放分别采用单独的控制芯片进行控制的模式，且将TD-SCDMA功放与GSM功放封装在一模块上应用到双模手机上，可减小硬件体积，降低制造成本。
摘要（英）：

The invention relates to a TD-SCDMA/GSM dual-mode handset radio-frequency power amplifier module, comprising a TD-SCDMA power amplification chip used for receiving and processing a TD input signal, a GSM power amplification chip used for receiving and processing a GSM input signal and a control chip electrically connected with the TD-SCDMA power amplification chip and the GSM power amplification chip and used for alternately controlling the TD-SCDMA power amplification chip and the GSM power amplification chip; the TD-SCDMA power amplification chip, the GSM power amplification chip and the control chip are integrated into a module, thus replacing the original mode in which a TD-SCDMA power amplifier and a GSM power amplifier are respectively controlled by separate control chips; the TD-SCDMA power amplifier and the GSM power amplifier are encapsulated on one module and applied in the dual-mode handset, thus reducing the volume of hardware and reducing the producing cost.
