摘要： An antenna is provided having a primary helical coil (102) and a secondary helical coil (104) contra-wound relative to the primary helical coil. Switchable coupling between the coils allows the antenna response to switch from lower to higher frequency responses within the same Ultra High Frequency (UHF) band. A bandwidth of the same physical length antenna can be increased up to twice the bandwidth or for a fixed bandwidth, the antenna length can be shortened. For the high frequency band, when the secondary helix is disconnected from the primary helix, the primary coil operates as a interferer notch out to improve interference rejection, to reject unwanted signals from nearby radios transmitting in frequencies separated by duplex spacing, such as Terrestrial Trunked Radio (TETRA) and cellular Global System for Mobile (GSM) communication bands.
摘要翻译：提供了具有相对于主螺旋线圈反向缠绕的主螺旋线圈（102）和次级螺旋线圈（104）的天线。线圈之间的可切换耦合允许天线响应在相同的超高频（UHF）频带内从较低频率响应切换到较高频率响应。相同物理长度天线的带宽可以增加到两倍带宽或固定带宽，天线长度可以缩短。对于高频带，当次级螺旋线与主螺旋线断开时，初级线圈作为干扰信号切口出来以改善干扰抑制，从在邻近无线电设备中发射以双工间隔分开的频率发射的无用信号，例如陆地集群无线电（TETRA）和蜂窝全球移动通信系统（GSM）通信频段。

摘要： A method and apparatus for a dual-feedback, amplifier limiter for providing a conditioned radio-frequency signal. The dual-feedback, amplifier limiter includes an input that receives a radio-frequency signal and a stacked amplifier including an input node coupled to the input, an output node, a first transistor configured as a common-base amplifier, and a second transistor configured as a common-emitter amplifier. The dual-feedback, amplifier limiter further includes an output coupled to the output node of the stacked amplifier. The output provides the conditioned radio-frequency signal. The dual-feedback, amplifier limiter further includes a radio-frequency feedback circuit coupled to the stacked amplifier. The radio-frequency feedback circuit includes a passive radio-frequency dependent reactive element in series with a radio-frequency feedback circuit resistor. The dual-feedback, amplifier limiter further includes an envelope control feedback circuit coupled to the stacked amplifier and including a current mirror and a reactive element loop filter.
