Web2 de jun. de 2002 · This paper presents two balun circuits derived from the lumped Lattice-type LC-balun. First the lumped LC-balun bridge elements are substituted by microstrip lines. This results in an improved performance at the 2nd and 3rd harmonic frequency for RF power amplifier output baluns. Secondly, the lumped Lattice-type LC-balun is extended … WebAt RF frequencies, the use of a balun is necessary for correct function of transmitters and antennas. If not, unwanted current flow and mismatches can increase interference …
