An admittance equation which Marchand balun with equal coupled-lines must satisfy is derived, basing on quasi-TEM mode parameters of microstrip coupled-line.
根据微带耦合线的准TEM模参数 ,推导出相同耦合线Marchand巴伦须满足的导纳方程 ,讨论了改善巴伦性能的方法———电容补偿法。
Comparison of geometrics with traditional Ballentine shows that Ballentine is limited and maybe misleading,which can be solved by geometrics.
与直观几何方法相比,传统的巴伦坦图存在一定的局限性和一些误导性错误,用几何图形法都可以得到有效解决,由此说明计量经济学一些基本概念通过几何原理图形化具有相应的作用和意义。
