The volume of work - 113 pages, on which 10 drawings and 10 tables. When writing the project used 10 sources.
Key words: its advantages, the development receiver, frequency synthesizer - INV,Divider with a variable coefficient dividing - ДПКД, divider with a fixed ratio dividing - ДФКД, phase automatic adjustment frequency - PLL.
the purpose of the work is:The Telenor Group network receiver (frequency synthesizer) .
manageable tasks:
1) scheme Selection build a synthesiser frequency;
2) to develop structural diagrams synthesiser frequency on the basis of a modern cell base;
(3) Select a synthesiser frequency for the design on the basis of a modern cell base;
4) Select reference generator;
5) Calculation of coefficients dividing ДПКД and ДФКД;
6) LPF calculation on a loop PLL;
(7) to consider security issues vital signs;
8) to calculate economic efficiency constructions INV;
the main results: Designed for multi-mode synthesizer technology Telenor Group, UMTS and GSM,Meets the requirements to the draft.
