本文报道了栅极振荡器阵列的锁相结果。首先，通过锁相环将中心频率为4.7 GHz、电调范围为300 MHz的压控栅极振荡器阵列锁定到频率合成器。其次，采用注入锁定的方法实现了4/SPL/4和6/SPL/6栅格振荡器阵列的锁定。在这两种方法中，安装在反射镜上的简单环状天线用于从/向阵列接收/注入信号。结果表明，锁相振荡器阵列的相位噪声性能得到了显著改善。
In this paper, we report the results of phase locking of grid oscillator arrays. First, a voltage-controlled grid oscillator array with a center frequency of 4.7 GHz and with a 300-MHz electric tuning range was locked to a frequency synthesizer through a phase-locked loop. Second, a 4 /spl times/ 4 and a 6 /spl times/ 6 grid oscillator arrays were locked by way of the injection locking. In both methods, a simple loop antenna mounted on the reflection mirror was used for taking/injecting signals from/to the array. Results show that the phase noise performance is improved significantly in the locked oscillator arrays.
