Abstract
Description
Claims (1)
- 무선 수신 장치에 있어서, 소정 중간주파수(FIF)와 동일한 VHF대의 주파수(FIO)를 출력하는 국부발진기수단과, 상기 국부 발진주파수(FIO)를 소정 체배하여 UHF대역의 체배주파수(FX)를 발생하는 주파수 체배수단과, UHF대역의 입력 주파수(FRF)와 상기 체배 주파수(FX)를 혼합하여 상기 중간 주파수(FIF)를 발생하는 주파수 변환수단과, 동일 주파수인 상기 중간주파수(FIF)와 국부 발진주파수(FIO)를 혼합하여 디지틀 복조하는 호모다인 리시버로 구성함을 특징으로 하는 한개의 국부 발진기를 사용한 소형 무선 수신장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
