- Abstract:
- An efficient way to design a down-converter assembly for the Ka-band millimeter system is presented, in which dielectric resonators(DR’s)are adopted in the Schottky barrier diode image recovery mixer and the local oscillator(LO).DR structures guarantee high frequency stability with an acceptable volume.The configurations of low noise amplifier, mixer and oscillator in the assembly are described and fabricated to estimate the chain performance.According to the verification results, the assembly exhibits the noise figure of less than 5 dB over 1 GHz frequency range, and the single-sideband phase noise(200 kHz offset from carrier frequency)of -70 dBc/Hz.Utilizing the DR structure, the frequency stability of the local oscillator is less than 60×10-6/℃.
- 介绍了一种用于毫米波系统的下变频器, 其中混频器采用了肖特基二极管镜频回收混频结构, 振荡器采用了DRO(dielectric resonator oscillator)结构以提高系统性能, 以保证在合适的体积内实现较高的频率稳定度.描述了系统中低噪声放大器、混频器、振荡器的性能, 用于评估系统链路性能, 最后合并制作在单个基片上.根据测试结果, 该下变频器的噪声系数在35 GHz处1 GHz频率范围内小于5 dB, 单边带相位噪声系数在偏离载波200 kHz处达到-70 dBc/Hz.由于采用了介质谐振结构, 本振的频率稳定度小于60×10-6/℃.
