SEMICONDUCTOR CIRCUIT MODULE

摘要

PROBLEM TO BE SOLVED: To improve circuit characteristic (wide range adjustment of gain, perfect flattening of gain and perfect elimination of distortion) by avoiding complication of circuit structure without confinement of specification when a varicap is used as a circuit element. SOLUTION: Constitution is performed in such a manner that the varicap diodes are contained in circuit elements at interstage between this stage FET and a prestage FET and circuit elements at interstage between this stage FET and a poststage FET. As a result, adjustment of each impedance of the interstages is performed by changing circuit constant of the circuit elements. COPYRIGHT: (C)2004,JPO&NCIPI
