ADJUSTABLE CIRCUIT PACKAGES AND METHODS FOR MANUFACTURING ADJUSTABLE CIRCUIT PACKAGES

Abstract

The invention relates to an adjustable circuit, for example, comprising an inductor coupled to a node and a primary capacitor coupled to a node. The adjustable circuit also includes a variable capacitor coupled to a node, such that the total capacitance of the circuit can be adjusted depending on the fixed capacitance of the primary capacitor and the variable capacitance of the variable capacitor. In one example, the inductor and primary capacitor are both included in the passive component, and the variable capacitor is in the semiconductor component. The variable capacitor allows the total capacitance to be changed for purposes such as, for example, capacitance correction to compensate for variations in production and / or adjustment to the operating frequency range used by wireless devices in a region of the world. The primary capacitor may be a higher-quality capacitor that contributes a larger share of the total capacitance than the variable capacitor. In addition, the split design also mentions a method for producing adjustable circuit board packages.
