摘要
振荡器工作在720和940 MHz，特征温度范围为25°C至200°C和250°C，分别提出。该振荡器采用典型集成电路制造技术设计在氧化铝衬底上。Cree SiC mesfet，薄膜金属-绝缘体-金属电容器和螺旋电感器，以及约翰逊微型芯片天线组成了电路。输出功率和相位噪声是温度和频率的函数。
Characterization of 720 and 940 MHz oscillators with chip antenna for wireless sensors from room temperature to 200 and 250 °C
Oscillators that operate at 720 and 940 MHz and characterized over a temperature range of 25 °C to 200 °C and 250 °C, respectively, are presented. The oscillators are designed on alumina substrates with typical integrated circuit fabrication techniques. Cree SiC MESFETs, thin film metal-insulator-metal capacitors and spiral inductors, and Johanson miniature chip antennas make-up the circuits. The output power and phase noise are presented as a function of temperature and frequency.
