Witryna18 maj 2024 · A number of key antenna types have an impedance of 50 Ohms including ZigBee, GSM, GPS, and LoRa. A mismatch in impedance leads to voltage and current reflections, and in RF setups this means that signal power will be reflected back to its source, the proportion being according to the degree of mismatch. 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 … Zobacz więcej Another parameter used to describe impedance matching is the voltage standing wave ratio (VSWR).
