摘　　要：应用异或逻辑运算,对输入信号进行非线性变换,产生偶次高阶谐波分量,实现二倍频功能.改进的异或门中,利用LC谐振回路作为异或门的负载,提取出希望得到的频率分量.利用三阶巴特沃斯低通滤波器,解决了芯片输入、输出接口问题.选用微带线和衬底接地的共面波导等不同结构的电感实现形式,充分利用了芯片面积.测试表明,芯片可以在22.62～23.24GHz频率范围内实现二倍频输出.The input signal is nonlinearly transferred through the function of XOR gate, so higher even order frequency components are gotten. Using LC tank circuit as the load of modified XOR, the frequency component desired can be extracted out. The problem in the chip’s input or output interface is solved by applying a three-order Butterworth low pass filter. In this chip, inductors are realized with microstrips or grounded coplanar waveguides according to their actual position, so the chip’s area is reduced. The test results show that the output frequency range in which the chip can work as a frequency doubler is between 22.62~23.24GHz.
