Beschreibung:
The design and use of multi-standard RF transceivers is the way to increase hardware flexibility and functionality, as well as to improve the flexibility of set-makers on the market. In the design of multi-standard RF transceivers the efforts will be directed towards improvement of hardware reusability, reconfigurability, programmability and flexibility. This will result in the launching of a software-defined radio.
Problems and solutions in the design of multi-standard RF front-ends on the system, circuit and implementation level have been addressed
Front-end architecture selection.- Broad-band polyphase filters.- Analysis of low-IF architectures.- RF and building block specifications.- A low-voltage folded switching mixer.- Multi-band reconfigurable complex mixer.- Reconfigurable multi-band LNA.- Reconfigurable multi-band RF front-end.- Conclusions.
