Summary on Grant Application Form |
|
The aims of this proposal are to develop lower noise octave tuning (including narrowband versions) varactor based oscillators offering phase noise performance 10-20 dB better than the best commercial varactor based units. These will then offer performance similar to that currently available from the fare more expensive commercial YIG oscillators but at a fraction of the cost (<5%).This proposal will also involve the further development of sapphire based dielectric resonator oscillators by improving the Q and making them tunable over a narrow range. This will enable phase locking to other sources. Similar tunable oscillators based on high Q BaTi03 resonators operating up to 30/40GHz will be developed. The puck shape and mounting network will be optimised to obtain the maximum unloaded Q and the correct loaded Q using printed and or suspended structures.High power amplifiers with low flicker noise utilising feedforward techniques and new flicker noise reduction methods will be investigated to enhance the performance of microwave/mm-wave oscillators.
