(EN) Radio frequency switch for diversity receiver
(ZH) 用于分集接收器的射频交换机
Abrégé
(EN) A diversity receiver switch includes at least one second stage switch configured to communicate with a transceiver. The diversity receiver switch may also include at least one first stage switch coupled between a diversity receiver antenna and the second stage switch(es). The first stage switch(es) may be configured to handle a different amount of power than the second stage switch(es). The diversity receiver switch may include a bank of second stage switches configured to communicate with a transceiver. A first stage switch may be configured to handle more power than each switch in the bank of second stage switches. Alternatively, the diversity receiver switch include a bank of first stage switches coupled between the diversity receiver antenna and a second stage switch. The second stage switch may be configured to handle more power than each of the first stage switches.
(ZH) 一种分集接收器交换机包括配置成与收发器通信的至少一个第二级开关。该分集接收器交换机还可包括耦合在分集接收器天线和第二级开关之间的至少一个第一级开关。第一级开关可被配置成处置与第二级开关不同的功率量。该分集接收器交换机可包括配置成与收发器通信的一排第二级开关。第一级开关可被配置成处置比这一排第二级开关中的每个开关更多的功率。可选地,该分集接收器交换机包括耦合在分集接收器天线和第二级开关之间的一排第一级开关。第二级开关可被配置成处置比第一级开关中的每个开关更多的功率。
