摘要
提出了一种基于0．13μm工艺，采用平面螺旋电感结构的宽带单片不平衡变压器。该电路的中心频率为23GHz。在中心频率附近，模拟结果显示，单端口损耗为8dB，在20-30GHz频率范围内，两端口信号幅度误差为1dB，相位误差为5°。
A monolithic broadband passive balun using planar-spiral inductor was designed. The transformer has a center frequency of 23 GHz. Simulation results showed that the transformer had a single-port power loss of 8 dB near the center frequency and that its amplitude and phase unbalance between two balanced ports were 1 clB and 50°respectively, in the frequency range from 20 GHz to 30 GHz.
