研究了双端口场效应管振荡器及其在空间功率合成有源阵列中的应用。所考虑的双端口振荡器由具有不同输入和输出端口的单个FET振荡器组成。这种类型的振荡器表现出增加锁定带宽的替代方法。结果给出了一个原型的五元线性阵列工作在6 GHz。在这种情况下，整个阵列由提供给第一振荡器的单个注入信号同步。该阵列表现出大于500 MHz的锁定带宽与0 dBm的注入信号。然而，辐射方向图的旁瓣电平低于-10分贝，只有300兆赫的这个范围。示出了主瓣随频率的变化。主瓣方向变化约为每100 MHz频率变化的7%。<<ETX>>
Investigations of two-port FET oscillators and their use in active arrays for spatial power combining are reported. The two-port oscillator considered consists of a single FET oscillator with distinct input and output ports. This type of oscillator exhibits increased locking bandwidth over alternative approaches. Results are given for a prototype five-element linear array operating at 6 GHz. In this case, the entire array is synchronized by a single injection signal supplied to the first oscillator. The array exhibited a locking bandwidth of greater than 500 MHz with a 0-dBm injection signal. However, the radiation pattern had sidelobe levels below -10 dB for only 300 MHz of this range. Variation of the main lobe with frequency is shown. The main lobe direction variation is about 7% per 100 MHz of frequency change.<<ETX>>
