The first thing to understand is that there is nothing intrinsically special about a 50 Ω impedance. This is not a fundamental constant of the universe, though you might get the impression that it is if you spend enough time around RF engineers. It is not even a fundamental constant of electrical … See more Considering how important impedance matching is in RF design, we shouldn’t be surprised to find that there is a specific parameter used to express the quality of a match. It is called the … See more Another parameter used to describe impedance matching is the voltage standing wave ratio (VSWR). It is defined as follows: VSWR=1+ Γ 1− Γ VSWR=1+ Γ 1− Γ … See more Web阿里巴巴大码女装法式不规则荷叶边短袖上衣女夏季胖妹妹遮肉显瘦百搭衬衫,女式t恤,这里云集了众多的供应商,采购商,制造商。这是大码女装法式不规则荷叶边短袖上衣女夏季胖妹妹遮肉显瘦百搭衬衫的详细页面。面料名称:网纱,主面料成分:兔毛,袖长:短袖,货号:t679243578667,品牌:其他 ... is attest and witness the same
