摘要： A microwave power sensor is disclosed which is capable of using diodes above their resonant frequency to sense the power of input microwaves. The power sensor includes a sensing diode (34, 90, 90′), a conditioning means (30, 79), and a tapered waveguide. For input waves having frequencies near and above the resonant frequency of the sensing diode, the output of the diode begins to be frequency dependent. That is, the diode outputs different DC signals for waves having different frequencies even though the power of the waves is the same. The conditioning means is adapted to offset the frequency dependence of the diode by varying the fraction of the input wave that is transmitted to the diode so as to cause the output of the diode to be relatively constant for waves having equal power but different frequencies. The conditioning means also provides a load impedance which matches the characteristic impedance of the input wave to minimize the reflection of the input wave. In addition, the conditioning means attenuates the input signal to ensure that the sensing diode operates in the square law region. The tapered waveguide (32, 86) receives the wave transmitted by the conditioning means and conveys it to the sensing diode. The waveguide is adapted to cause the input wave to have a voltage maximum at its output port. By attaching the sensing diode across the output port of the waveguide, the power sensor is capable of sensing the power of input waves having frequencies over a broad frequency band.

摘要翻译： 公开了一种微波功率传感器，其能够在谐振频率之上使用二极管来感测输入微波的功率。 功率传感器包括感测二极管（34,90,90分钟），调节装置（30,79）和锥形波导。 对于具有接近和高于感测二极管的谐振频率的频率的输入波，二极管的输出开始是频率依赖的。 也就是说，即使波浪的功率相同，二极管对具有不同频率的波也输出不同的直流信号。 调节装置适于通过改变传输到二极管的输入波的分数来补偿二极管的频率依赖性，以便使二极管的输出对于具有相同功率但不同频率的波相对恒定。 调节装置还提供与输入波的特性阻抗匹配的负载阻抗，以最小化输入波的反射。 此外，调节装置衰减输入信号，以确保感测二极管在平方律区域中运行。 锥形波导（32,86）接收由调节装置传输的波并将其传送到感测二极管。 波导适于使输入波在其输出端口具有最大电压。 通过将感测二极管连接在波导的输出端口上，功率传感器能够感测在宽频带上具有频率的输入波的功率。
