Abstract
A apparatus for dynamically modifying filter characteristics of a delta-sigma modulator in order to receive and transmit radio frequency signals over a wide frequency range. The system is used for wide bandwidth radio system designed to adapt to various global radio standards and, more particularly, to a cellular radio architecture that employs a combination of a single circulator, programmable band-pass sampling radio frequency (RF) front-end and optimized digital baseband that is capable of supporting all current cellular wireless access protocol frequency bands.
