Web28 Feb 2024 · The balun’s function is to transfer power between balanced and unbalanced systems (usually a feed line and a load that can be a circuit or an antenna) in either direction. At the same time, it isolates the unbalanced and balanced systems from getting to the balanced system. WebOur BAL-0003, BAL-0006, and BAL-0010 are instrumentation grade 50 Ω input: 50 Ω output (100 Ω differential) baluns with excellent phase and amplitude match to kHz frequencies. The high power balun variations (the BALH-0003, BALH-0006, and BALH-0010) can be used as either 1:1 or 1:2 transformers (that is either 100 Ω or 50 Ω differential ...
