专利汇可以提供Resonance circuit forming method for uhf tuner专利检索,专利查询,专利分析的服务。并且PURPOSE:To make the mounting of components easy and to avoid mounting in error, by removing unnecessary linking parts after mounting the components, in blanking the resonance line of each resonance circuit of a tuner from the same metallic plate. CONSTITUTION:A resonance line L1 of input section, resonance line L2 of local oscillation section, and resonance lines L3, L4 of in-stage and mixer section are formed by blanking while leaving a linking section 14 from one metal plate 13. Thereafter, varactor diodes D1-D4 with arranged electric characteristics are provided at a prescribed location of the frame and the resonance lines. The varactor diodes are coupled with cream solder. The linking section 14 of the resonance line is eliminated. Thus, the holding of a resonance line can be made simple and stable while mounting a plurality of components and job can be progressed with confirmation.,下面是Resonance circuit forming method for uhf tuner专利的具体信息内容。
