| 摘 要： | 对Ka频段三端器件漏极混频器电路进行了分析和优化设计。由三端器件小信号S参数和直流特性测试值拟合出该器件非线性等效电路模型和参数；采用谐波平衡和变换矩阵分析法推导出漏极混频器变频增益，由此优化设计混频器电路。实验测试结果射频为27.4GHz、本振为33.4GHz/10dBm，获得变频增益为4dB。

| Abstract: | The analysis and optimizing design for three port device drain mixer in Ka band were given. The nonlinear equivalent circuit and its parameters were simulated and obtained from the small signal S parameter and the DC measurements of three port device. And then, the drain mixer circuit was designed with optimum conversion gain of the drain mixer which was derived from the harmonic balance method and the conversion matrices method. The test result shows that the mixer has conversion gain 4dB at RF 27.4GHz and LO 33.4GHz/10dBm. |
