Dual Mode Hybrid PLL Based Frequency Synthesizer for Cognitive Multi- radio Applications

Résumé

This paper investigates a novel approach to implementation of multiband frequency synthesizer for cognitive multi-radio applications. The architecture here considered employs a dual-mode PLL (Phase Locked Loop) based frequency synthesizer for data applications, which is capable to switch between a fractional wideband high speed mode and an integer, narrowband and low spur mode after the settling. A secondary integer-N PLL synthesizer is proposed for voice applications. Both synthesizers are driven by the same reference oscillator. The overall architecture is described here and simulated along with frequency plan considering the most diffused standards in the band from 500 MHz to 6 GHz.
