description: The subject of the graduate qualification work: "Development of an electrically tunable band-pass filter based on ferroelectric varactors for a decimeter range receiver". This given work is devoted to the development of an electrically tunable bandpass filter based on ferroelectric varactors for a decimeter range receiver. In masterâs thesis the structure of a tunable microstrip filter based on ring resonators was calculated using a nonlinear model of a ferroelectric varactor. The varactor model was calculated based on the characteristics of a real ST Microelectronics varactor. The result is a filter designed for three operating states. It has an electrical tuning range from 0.87 to 2.5 GHz, a bandwidth of 200-300 MHz, a stopband rejection of more than 30dB, and a passband loss and ripple of less than 5dB and 3dB, respectively. The task was completed in full.
