Electronically Tunable Amplifier.
Abstract
This report describes a research effort intended to determine the feasibility of combining high power solid state amplifier and electronically tunable resonator technology. This new technology would be applicable to the design and fabrication of high power electronically tunable amplifiers capable of frequency agile operation in the UHF range. The primary goal of the effort was to determine if the RF power from twelve 100 watt solid state amplifier modules could be combined in the electric field of an electronically and/or mechanically tuned cavity resonator, to produce/kilowatt of continuous output power. Testing of the experimental model showed that efficient RF power combining could be obtained in a mechanically tuned cavity where the length of the coaxial inner element was varied to change the frequency. Summing with the electronic tuning technique (PIN diode switched loops) was inefficient and distortion of the RF field by the tuning loops within the cavity precludes tuning and summing at the same time.
