    • A receiver (10) includes an antenna (12), a preselector (14), an amplifier (16), a mixer (18), a filter (20), a signal strength measurement circuit (22), a radio frequency signal detector (26), and a processor (24). The processor (24) is programmed to receive a signal indicator level (42) from the signal strength measurement circuit (22), generate an automatic gain control command (44) based on the received signal indicator level (42), and send the automatic gain control command (44) to the amplifier (16) to control a gain of the amplifier (16). The processor (24) is programmed to receive an off channel signal strength (48) from the radio frequency signal detector (26), compare the off channel signal strength (48) to one or more threshold levels, generate a filter command (46), and send the filter command (46) to the filter (20). The filter command (46) identifies a cutoff frequency for the filter (20).
    • 接收器(10)包括天线(12),预选器(14),放大器(16),混频器(18),滤波器(20),信号强度测量电路(22),射频信号检测器 (26)和处理器(24)。 处理器(24)被编程为从信号强度测量电路(22)接收信号指示器电平(42),基于接收到的信号指示器电平(42)产生自动增益控制命令(44),并发送自动 增益控制指令(44)到放大器(16)以控制放大器(16)的增益。 处理器(24)被编程为从射频信号检测器(26)接收离开信道信号强度(48),将关闭信道信号强度(48)与一个或多个阈值电平进行比较,生成滤波器命令(46) ,并将过滤器命令(46)发送到过滤器(20)。 滤波器命令(46)识别滤波器(20)的截止频率。

    • A stripline split-ring resonator bandpass filter comprises first and second conducting layers and first and second substrates connected to each other between the conducting layers. A first stripline ring resonator is located on the top side of the second nonconducting substrate and is coupled to the input port of the BPF. The first stripline ring resonator has a gap located therein. A second stripline ring resonator is also located on the top side of the second nonconducting substrate between the first stripline ring resonator and the output port of the BPF. The second stripline ring resonator has a gap located therein. The first substrate has at least two slots therein to allow lumped capacitors to be placed in the gaps in the first and second ring resonators.
    • 带状线分离环谐振器带通滤波器包括第一和第二导电层以及在导电层之间彼此连接的第一和第二基板。 第一带状线环谐振器位于第二非导电衬底的顶侧,并且耦合到BPF的输入端口。 第一带状线环谐振器具有位于其中的间隙。 第二带状线环谐振器也位于第二非导体衬底的顶侧,位于第一带状线环谐振器和BPF的输出端口之间。 第二带状线环谐振器在其中具有间隙。 第一衬底在其中具有至少两个槽,以允许集中的电容器放置在第一和第二环形谐振器的间隙中。
