1999-09-09 DSP tips for designing a DECT/GSM fractional-N frequency synthesizer
This paper describes how to implement a fast and flexible frequency divider in a fractional N frequency synthesizer in a dual-mode transmitter for DECT/GSM with a high component reuse. The divider is described in VHDL and simulated for one of the two standards.
1999-09-09 SAW filters in CDMA mobile communication networks
Surface Acoustic Wave (SAW) filters are used in the intermediate frequency (IF) filtering stage for both the Code Division Multiple Access (CDMA) handset and infrastructure. They are preferred over other types of filter technologies because SAW filters demonstrate high performance yet low cost and small size. This paper describes the evolution of SAW designs to meet the challenging demands of reducing the size and cost for CDMA IF filters.
