Abstract

The reduction of interfering influences in an LC resonant circuit with an integrated circuit is effected by including the interfering elements of the housing in the resonant circuit. This precludes the occurrence of parasitic radio-frequency oscillation modes. It also ensures good radio-frequency properties and a wide frequency tuning range.
