Fully integrated frequency-phase generators for a 6-18GHz wide-band phased-array receiver element are presented that generate 5-7GHz and 9-12GHz first LO signals with less than -95dBc/Hz phase noise at 100kHz offset. Second LO signals with digitally controllable fourquadrant phaseand amplitude spread with better than 3 resolution are generated and allow removal of systematic reference clock ske...

T his is the final article in a five-part series on microwave frequency synthesizers. It concludes with a review of advanced synthesizer solutions. Although synthesizers can be found in virtually any microwave system, test and measurement (T&M) is probably the most challenging application that calls for advanced synthesizer techniques. This final article addresses some specific T&M requirements...

Microsimulation models that forecast the activities and travel of urban populations create synthetic populations and then use them to simulate the behavior of the households and persons in that synthetic population. The features of eight population synthesizers are compared, and suggestions are made for incorporating the best features into future population synthesizers. Author’s note The autho...

Phase locked loops for fractional frequency synthesis typically use Digital $\Delta \Sigma $ Modulators (DDSMs) as their divider controllers. Different types and configurations of DDSMs have been presented in the past which distinctiv...

The main technological issues and circuit design challenges arising in the development and manufacturing of the RF front-end electronics for the next generation (terrestrial or space-born) radio communication and remote sensing systems will be synthetically outlined, with the aim of also pointing out both the specific design tool requirements and a number of related research topics. Actually, t...
