    • Techniques to control shared antenna architectures for multiple co-located radio modules are disclosed. The shared antenna architecture may include a combiner and at least one bypass switch for enabling simultaneous operations or mutually-exclusive operations of multiple transceivers. Dynamic gain control is employed to accommodate different front-end losses associated with a variety of signal paths that are achievable using the switch and combiner. Such dynamic gain control can include selecting from multiple sets of amplifier gain values that are tailored to meet the needs of the particular applications that are active at a particular time. Gain values can be chosen based upon received gain information including characteristics including a desired path loss, an application demand, a radio module type, a path configuration, and a mode of operation. By providing dynamic selection of gain values based on application demands, range and throughput of the transceivers can be attained. Other embodiments are disclosed and claimed.
    • 公开了用于控制多个同位置无线电模块的共享天线体系结构的技术。 共享天线架构可以包括组合器和至少一个旁路开关,用于实现多个收发器的同时操作或相互排斥的操作。 使用动态增益控制来适应与使用开关和组合器可实现的各种信号路径相关联的不同前端损耗。 这种动态增益控制可以包括从多组放大器增益值中选择,这些放大器增益值被调整以满足在特定时间处于活动状态的特定应用的需要。 可以基于接收到的增益信息来选择增益值,增益信息包括期望的路径损耗,应用需求,无线电模块类型,路径配置和操作模式的特性。 通过根据应用需求提供增益值的动态选择,可以实现收发器的范围和吞吐量。 公开和要求保护其他实施例。
