Hybrid circuit for impedance matching circuit used in mobile communication apparatus, has adjustable impedance elements which are designed based on different technologies, different physical effects and different action principles

摘要

The hybrid circuit (H) has adjustable impedance elements e.g. varactor whose impedance is adjusted by respective inner control signals. The adjustable impedance elements are designed based on different technologies, different physical effects and different action principles. The inner control signals provided to respective adjustable impedance elements, are different from one another.
