技术教程 共模电感应用说明
一般在选用共模电感的时候重点注意以下几个参数:
1) Impedance 表示器件在100MHz 时最大的阻抗值。一般在应用共模电感时候,
都是以此值作为选用的重点参考。
2) Rated Current 表示器件应用时候的最大额定电流。在选用的时候,这个参
数作为此重点,电路工作电流一定要小于器件额定工作电流,不然容易烧毁器件。
3) 至于 ...
模拟电子 简化精密测量的高输入阻抗ADC
 
High input impedance and a wide input range are twohighly desirable features in a precision analog-to-digitalconverter, and the LTC®2449 delta-sigma ADC has both.With just a few external components, the LTC2449 formsan exceptional measurement system with very high inputimpedance and a ...
模拟电子 DN454 单端至差分放大器设计技巧
 
A fully differential amplifi er is often used to converta single-ended signal to a differential signal, a designwhich requires three signifi cant considerations: theimpedance of the single-ended source must match thesingle-ended impedance of the differential amplifi er,the amplifi er&rsqu ...

Radio Frequency Integrated Circuit Design
I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog i ...

Calculation of the Differential Impedance of Tracks on FR4 substrates
There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to ...

阻抗匹配
阻抗匹配(Impedance matching)是微波电子学里的一部分,主要用于传输线上,来达至所有高频的微波信号皆能传至负载点的目的,不会有信号反射回来源点,从而提升能源效益。 大体上,阻抗匹配有两种,一种是透过改变阻抗力(lumped-circuit matching),另一种则是调整传输线的波长(transmission line matchi ...
电源技术 优化输电线路 精确测量电压驻波比(VSWR)
Abstract: Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss andreflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line imperfections. Thistutorial defines VSWR and explains how it is calculated. Finally, an antenna VSWR ...
