摘要：

This paper describes an effort to develop a DRO module as a silent oscillator candidate in the S-band radar system using (Mg1-xZnx)TiO3 ceramic with x(Zn) = 0.05-0.45 (Hereinafter referred to as MZT0.05-MZT0.45) as the resonator material. To improve the DRO's characteristics-particularly its output power-above zero, efforts were made by employing the ceramic pucks with an 8-mm diameter. The ceramics underwent five hours of sintered heat at 1300 degrees C. XRD, SEM-EDX, and Network Analyzer were used to examine the ceramics' structure, microstructure, and dielectric properties. The N9020A MXA Spectrum Analyzer in transverse electric (TE01 delta) mode was used to measure the DRO properties. The DRO resonant frequency was recorded as stable for one hour at 3.35-3.38 GHz with positive output power (+ 3.57)-(+ 3.95) dBm, narrow bandwidth (58 kHz) and low phase noise (- 62.9)-(- 68.3) dBc/Hz at 100, 300, 700 kHz and 3 MHz offset frequencies. Temperature stability of the resonance frequency was attained after conducting continuous measurements from 25 to 65 degrees C. These data reveals that the MZT0.05-MZT0.45 ceramics are promising DRO materials for using as a silent resonator in S-band radar system.
