Circuit for mobile communication devices, has variable capacitance and parallel interconnected branches, where each branch comprises basic element with adjustable capacitance

摘要

The circuit (SvK) has variable capacitance and parallel interconnected branches, where each branch comprises a basic element (GG) with adjustable capacitance. The basic element has two capacitive elements (eKE,zKE), where the capacitance of former capacitive element is infinitely adjusted. An impedance matching circuit is provided for Wideband code division multiple access, Global system for mobile communication, or Long term evolution-transmission system.
