摘　　要：采用双耦合ＹＩＧ谐振子和单元化设计技术，设计了一种 ＣＸ双波段 ＹＩＧ调谐ＦＥＴ振荡器。以阻抗国图形式给出了ＣＡＤ优化设计的计算结果，稳定因分析表明理论设计与实验结果一致。样品测试结果为，频率范围 ４－１２.６ＧＨｚ，输出功率大于 １３ｄＢｍ，线性度 ±０．２２７％，功率波动８ｄＢ。An YIG-tunned FET oscillator covering CX double-band have been designed using dual coupling YIG resonator and unitized design technology. The calculation results of CAD optimization design have been given in impedance circle-figure, and stabilization-circles analyses indicate that the theory design is in accordance with experiment result. The test results show that frequency range of 4-12.6GHz, output power of higher than 13dBm, linearity of ±0.227% and power variation of 8dB are reached.
