具有组合输出的低噪声放大器
摘要：
本发明公开了具有组合输出的多个低噪声放大器（LNA）。在一个示例性设计中，一种装置包括前端模块和集成电路（IC）。前端模块包括具有被组合的输出的多个LNA。IC包括经由单个互连耦合至该多个LNA的接收电路。在一个示例性设计中，该多个LNA中的每一个LNA可经由该LNA的相应控制信号来启用或禁用。前端模块还可包括耦合至该多个LNA的接收滤波器以及耦合至这些接收滤波器的开关共用器。前端模块可进一步包括至少一个功率放大器，并且IC可进一步包括耦合至该至少一个功率放大器的发射电路。
摘要（英）：

Multiple low noise amplifiers (LNAs) with combined outputs are disclosed. In an exemplary design, an apparatus includes a front-end module and an integrated circuit (IC). The front-end module includes a plurality of LNAs having outputs that are combined. The IC includes receive circuits coupled to the plurality of LNAs via a single interconnection. In an exemplary design, each of the plurality of LNAs may be enabled or disabled via a respective control signal for that LNA. The front-end module may also include receive filters coupled to the plurality of LNAs and a switchplexer coupled to the receive filters. The front-end module may further include at least one power amplifier, and the IC may further include transmit circuits coupled to the at least one power amplifier.
