Tuning component for printed circuits - consists of disc metallised on one side and containing conducting patterns forming variable couplings and reactances

摘要

The tuning component for printed circuits consists of a disc metallised on one side. The disc is rotatable about a pin in the circuit board. Conducting patterns are produced on the disc side facing the circuit board. They form with opposite conducting configurations variable couplings, reactances or stubs, matching units for circuits and semiconductors. The disc is mounted on the pin, with a dielectric layer of any permittivity and thickness between it and the circuit board. It is easily dismountable.
