ABSTRACT:
An oscillator (200) with improved sideband noise is disclosed. This improvement is accomplished without affecting the Q or the output power of the oscillator (200). The improvement is realized by increasing the rate of change of reactance over frequency. The increase in the rate of change is realized by placing two transmission lines (208, 210) in close proximity of each other. This increase assures oscillation while minimizing the sideband noise, and providing maximum bandwidth.
