A Wideband MMIC-based Feedback Oscillator

Classic feedback oscillators have often been favored because of their low phase noise performance and wide frequency tuning characteristics. This article covers the basic theory of feedback oscillators, and shows how the addition of a vector modulator ...
The requirement for increased data rates in modern radio systems has led to higher order modulation schemes which, in turn, demand oscillators with lower phase noise. Meanwhile, manufacturers must also deliver low cost solutions covering many different frequency bands. These two criteria have generally been incompatible, since an improvement...
