웹Step 4: Measurements. To check the transformation ratio of 1:9, the balun has been measured with a VNA. In this measurement the balun is connected to a 470 ohms resistor (the impedance of the VNA port is 50 ohms). As we can see on the picture, the balun assure a bandwidth going from 3 MHz up to 50 MHz with the respect of SWR of 2:1. http://www.in3eci.it/index.php?fl=5&op=mcs&id_cont=257&idm=301 mcm301 short notes웹2016년 8월 12일 · In fact, the 9:1 unun that I built is actually an autotransformer. Here’s a video that talks a little bit about autotransformers.. It’s relatively easy to build a 9:1 balun. One of the most common designs is to wind nine turns of a trifilar winding around a toroid core. Trifilar means that there are three wires wound simultaneously around the core. mcm301 - communication skills handouts
