本文报导了一种单调谐体效应振荡器.该振荡器结构类似于Kurkoawa电路.但谐振腔采用H_(011)高Q圆柱腔.该振荡器电路负载变化对振荡频率影响较小,能够避免通常反射腔稳频振荡器受到负载变化可能出现跳频的缺点.而且噪声电平比其它振荡源要小.对电路参数经过适当选择后,振荡器的输出效率能达到40～60%,输出功率30～100mW.机械牵引带宽大于600MHz.该振荡器的主腔和调谐活塞采用线胀系数不同的材料进行温度补偿.当温度循环在-40℃至+70℃的范围内,频率温度系数一般优于0.08MHz/℃,功率稳定度优于0.022dB/℃.
This paper reports a monotonic body-effect oscillator that is similar in structure to a Kurkoawa circuit, but uses a H_ (011) high-Q cylindrical cavity in the resonator. This oscillator circuit load variation has less effect on the oscillation frequency, Reflected cavity frequency stabilization oscillator is subject to the disadvantage of frequency hopping when the load is changed, and the noise level is smaller than other oscillator sources. After the circuit parameters are properly selected, the output efficiency of the oscillator can reach 40-60% and the output power 30 ~ 100mW. The mechanical traction bandwidth is greater than 600MHz. The oscillator's main chamber and tuning piston are temperature compensated with materials with different coefficients of linear expansion. When the temperature cycling is in the range of -40 ° C to + 70 ° C, the frequency temperature coefficient is generally better 0.08MHz / ℃, the power stability is better than 0.022dB / ℃.
