In November 1781, John Hanson became the first President of the United States in Congress Assembled, under the Articles of Confederation. Many people have argued that John Hanson, and not George Washington, was the first President of the United States, but this is not quite true.
Even and odd mode impedances of a coupled microstrip line. actually I find the reason when you use differential port, the impedance you get is twice the odd mode impedance, whereas if you use common port, the impedance is half the even mode impedance. 1 members found this post helpful.
PLANET FT-80x is a Fast Ethernet Bridge 100BASE-FX fiber to 10/100BASE-TX shielded twisted pair (STP) converter. It supports both half-duplex and full-duplex operations and a variety of fiber options. The converter auto-adapts to the highest level of performance supported by the device connected to the STP port.
