Abstract :
In this letter, a novel low temperature cofired ceramic (LTCC) miniaturized dualband balun using a tapered line structure has been presented. The key concept for our dualband solution is by employing tapered line structures in the conventional Marchand baluns. In our new design, we have demonstrated the tapered line structure can shift the periodic operation frequency to a desired frequency band. A sample balun design has been presented. The novel LTCC dualband balun has been simulated and verified by measurement. The measured results exhibit that the proposed balun can easily cover the important radio frequency bands at 2.4GHz, 5.25GHz, and 5.85GHz.
