Abstract
PURPOSE:To reduce number of circuit components by constituting a feedback capacitance between terminals of an active component, an inductive element, an active element and a capacitive component having the coupling capacitance to the next stage with the active element by the electrode pattern provided to both faces of the one high dielectric constant board. CONSTITUTION:The electrode pattern 17 is provided on the surface of the feedback capacitance between the base and emitter and the electrode pattern 18 in pairs with the electrode pattern is provided on the rear face and the electrode pattern 18 is connected to the emitter electrode of the surface through a through holes 19 of both the sides. That is, a capacitance exists definitely between the electrode pattern 17 on the surface and the electrode pattern 18 of the rear side and the feedback capacitance between the base and emitter is formed in a conventional device. Similarly. the feedback capacitance between the emitter and ground is formed by the electrode pattern 20 and the electrode pattern 21 of the rear side or and the collector and inductive element and the emitter and the coupling capacitance to the next stage are formed respectively by electrode patterns 22-25. Thus, the number of mounted components is reduced.
