Abstract

이중 슈퍼헤테로다인 무선수신기에 있어서, 기본형 2폴 크리스탈필터를 이용한 중간 주파수증폭 회로에 관한 것이다.In a dual superheterodyne wireless receiver, the present invention relates to an intermediate frequency amplifier circuit using a basic two-pole crystal filter.

하나의 기본형 2폴 크리스탈필터를 이용하여 중간 주파수 증폭회로를 구현함으로써 원가절감 효과 및 생산성향상을 가져오고 회로기판상의 부품수 감량에 따른 소형 경량화를 꾀한다.Implementing an intermediate frequency amplification circuit using one basic two-pole crystal filter brings cost reduction and productivity improvement and miniaturization and weight reduction due to the reduction of the number of parts on the circuit board.
