Abstract :
This paper presents an optimized design technique for direct conversion wireless transceivers. A cascade multimode filtering structure composed of a comb filter followed by a half-band and a FIR filters is defined for both GSM and DECT standards. A practical method, which can be easily applied to any standard, is proposed to look for relaxed filter specifications in multistage structure. Good performances with low complexity architecture are obtained.
