    • The present invention discloses a PCI-Express multimode expansion card comprising a PCI-Express interface port for insertion into a PCI-Express slot of a motherboard, a PCI-Express expansion port, a USB expansion port, and a jumper circuit connecting the PCI-Express interface port and the two expansion ports. The PCI-Express expansion port provides expandability by allowing the attachment of a PCI-Express interfaced peripheral device, and the USB expansion port provides expandability by allowing the attachment of a USB-interfaced peripheral device. As such, a single PCI-Express multimode expansion card inserted into a PCI-Express slot configured on the motherboard can be used to attach two peripheral devices with different interface, thereby achieving the function of multimode expansion.
    • 本发明公开了一种PCI-Express多模扩展卡,其包括用于插入主板的PCI-Express插槽的PCI-Express接口端口,PCI-Express扩展端口,USB扩展端口和连接PCI- Express接口端口和两个扩展端口。 PCI-Express扩展端口通过允许连接PCI-Express接口的外围设备来提供可扩展性,并且USB扩展端口通过允许连接USB接口的外围设备来提供可扩展性。 因此,插入到主板上配置的PCI-Express插槽中的单个PCI-Express多模扩展卡可用于连接具有不同接口的两个外围设备,从而实现多模扩展的功能。

    • An extended range received signal strength indicator module includes input lines connected to a variable gain amplifier, which passes the amplified RF signal to a polyphase, which in turn passes the filtered signal to a series of RSSI stages. Each RSSI stage includes a log amplifier and outputs an amplified current to a current summer as well as to the next RSSI stage in the series. The current summer outputs the sum of the received currents to RSSI_OUT. An additional frequency filter and RSSI stage with inputs connected to the input lines before the variable gain amplifier that outputs the modified current to the current summer is also included. A control circuit switches the additional RSSI stage on or off as determined by a detection circuit that monitors the value of RSSI_OUT.
    • 扩展范围接收信号强度指示器模块包括连接到可变增益放大器的输入线,该可变增益放大器将放大的RF信号传递到多相,其又将经滤波的信号传递到一系列RSSI级。 每个RSSI级包括对数放大器,并将放大的电流输出到当前夏天以及串联中的下一个RSSI级。 当前的夏天将接收电流的和输出到RSSI_OUT。 还包括一个额外的频率滤波器和RSSI级,其输入端连接到可变增益放大器之前的输入线,输出修改后的电流至当前夏季。 控制电路根据监视RSSI_OUT的值的检测电路来确定开启或关闭附加RSSI级。
