Abstract

Due to confined space in a stack of reduced height waveguides, power detection of the incident and reflected wave in the reduced height waveguide is extremely difficult. A new compact probe to monitor the incident and reflected wave from the narrow side of the reduced height waveguide has been developed. This compact probe consists of 2 current loops, a directional coupler, and a small trimmer capacitor. The two current loops are placed on the narrow side of the waveguide with a quarter guide wavelength (/spl lambda//sub g//4) spacing. The outputs of the current loops are connected to the directional coupler. In order to optimize phase adjustment, a trimmer capacitor is attached in series with one of the current loops. Test results show that more than 30 dB directivity at 4.6 GHz is achieved by using this compact probe.

紧凑的探头设计，用于从降低高度波导的窄侧进行功率监测

由于降低高度波导堆栈的空间有限，降低高度波导中入射波和反射波的功率检测非常困难。研制了一种新型的小型探头，用于从降高波导的窄侧监测入射波和反射波。这种紧凑的探头由2个电流回路、一个定向耦合器和一个小微调电容器组成。两个电流环以四分之一波导波长(/spl lambda//sub g//4)间隔放置在波导的窄边。电流回路的输出连接到定向耦合器。为了优化相位调整，在其中一个电流回路上串联了一个微调电容器。测试结果表明，该探头在4.6 GHz下的指向性可达30 dB以上。

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
