WebLine Transformer Balun – Baluns are also used as a simple form of a transmission line transformer. They commonly use a small ferrite core in a toroidal or binocular shape that often only consist of 10 turns of a coaxial cable that is smaller than the size of a dinner plate. WebA balun is a type of transmission line transformer. This two-port component is placed between a source and load when a differential symmetric RF functional block needs to be connected to a single-ended block. These transformers are made by winding a strip-line on a high-permeability core substrate. Because of the high impedance of the winding ...

Advantages of Balun disadvantages of Balun - RF Wireless World

WebWinding the transmission-line on the toroid-core makes a choke; hence the name “choke-balun”. The choke has a reactance and it serves to isolate the input from the output and works to prevent conventional transformer currents; we want that reactance to be at least 5 times (some authors say 10x) the load resistance. Webtransmission lines are called unbalanced or single-ended. Among the frequently used line types of the single-ended family are the coaxial line, the microstrip line, and the coplanar line. In microstrip transmission line, for example, one of the two conductors is a metallic strip, the other one is represented by a conductive plane. WebThe term balun is a portmanteau of balanced and unbalanced, indicating that a balun will transition between a balanced (also called ‘differential’) transmission line (where opposite currents both travel in transmission lines) and an unbalanced (also called ‘single ended’) transmission line (where the return current travels in the ground). However, this … diversity leadership development program
