Direct Conversion receiver adapting DC offset free diode mixer
직접 변환수신기 (direct conversion receiver)에 적합한 DC offset이 없는 주파수 변환기를 채용한 직접변환 수신기의 설계
Abstract
One of the problems using DCR(Direct Conversion Receiver) are DC offset, poor channel selectivity. APDP(Anti Parallel Diode Pair) can be good candidate for DCR frequency mixer due to its inherent End harmonic suppression. APDP shows good IP2 and DC suppression. This paper describe single APDP LO power characteristics, IP2, and receiver structure utilizing APDP frequency mixer
