A Voltage Tunable Oscillator in L-Band
Abstract
Development of a voltage-tunable planar-triode oscillator in the 500 to 1000 mc range was undertaken to assess the capabilities of ferroelectric materials as tuning elements. The frequency range was chosen in response to a general requirement for L-band voltage-tunable oscillators and to demonstrate the ability of ferroelectrics to operate at frequencies beyond the useful range of available diode tuning capacitors. A 500-mc oscillator was constructed using a planar triode tube. The oscillator could be tuned electrically over a 15 per cent bandwidth. The tuning was accomplished by a solid element with low-power drain and no moving parts. A discussion of the tuning element, tuning technique, circuit design, limitations and some possible improvements is included.
