Design And Development Of A 3.6 GHZ Dielectric Resonator Oscillator With Wide Tuning Sensitivity
An oscillator is required as a second stage LO in a superheterodyne SA. The oscillator operating frequency is a fixed 3.6 GHz, which is at the lower end of the microwave frequency range. There are several options of active devices and resonators that can be considered for the oscillator. A bipolar...

| description |
An oscillator is required as a second stage LO in a superheterodyne SA. The oscillator operating frequency is a fixed 3.6 GHz, which is at the lower end of the
microwave frequency range. There are several options of active devices and resonators that can be considered for the oscillator. A bipolar junction transistor (BJT) is chosen for the amplifier block due to its low flicker noise corner frequency and a dielectric resonator (DR) is chosen for its high Q factor. This combination yields a low phase noise oscillator. Apart from its high Q factor, a DR is a high dielectric constant ceramic thus enabling a miniaturized microwave oscillator design compared to a cavity resonator. A varactor-tuned technique is adopted because it results in a simple planar circuit design compared to optically and magnetically tune DR. |
