Baluns and ununs are essential in RF signal chains for many applications. RF balun designs are most commonly associated with core-and-wire transformers, but can also be realized through coaxial and coupled stripline technologies. The behavior of baluns and ununs was introduced in Part 1 of this series, where we … 더 보기 The most common use for baluns is when a single-ended power amplifier is used to drive a balanced load. Examples include dipole antennas or single-ended antennas such as whips, which are needed to feed an additional front-end … 더 보기 Baluns share most of the same performance parameters as RF transformers, but the unique construction and use of baluns introduces additional considerations. These parameters include: 1. Phase balance 2. … 더 보기 Before tackling balun theory, it is important to understand the differences between balanced and unbalanced two-terminal sources and loads. In a … 더 보기 There are two main modes of baluns: current baluns and voltage baluns (see Figure 3). Current baluns operate by forcing equal currents on both balanced lines, effectively eliminating common-mode currents. Voltage … 더 보기 웹2013년 3월 26일 · Der Name Achterstag-Balun wird oft verwendet, ist aber nicht richtig und müsste statt dessen Unun heißen, da ja nichts Symmetriert wird. Der Eingang und Ausgang, oder umgedreht, sind unsymmetrisch. Fälschlicher Weise wird er sehr oft, sogar auch in Bootszubehörkatalogen, als Balun oder Achterstag-Balun bezeichnet.

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. headphones repair service
