Abstract
A UHF-feedback oscillator for a frequency range of at least 300 MHz to 1000 MHz includes an amplifier stage, a voltage controlled tuning filter and a feedback quadripole. The feedback quadripole comprises a two- or three- loop helical waveguide resonator. Thus, the oscillator is easily adjustable to its oscillating condition within the very wideband frequency range of between 300 MHz and 1000 MHz and can be miniaturized in the simplest manner.
Claims5
A UHF-feedback oscillator for a frequency range of at least 300 MHz to 1000 MHz comprising an amplifier stage, a voltage controlled tuning filter connected to said amplifier stage and a feedback quadripole connected between said amplifier stage and said filter, said feedback quadripole comprising one of a two- and three-loop helical waveguide resonator.
A UHF-feedback oscillator, in particular for the frequency range of 300 MHZ to 1000 MHz, comprising a connected together amplifier stage, voltage controlled tuning filter and feedback quadripole, said quadripole comprising a two-loop waveguide resonator or a three-loop waveguide resonator.
