采用新的设计方法设计了四位 CMOS 步进衰减器，以实现改善的平坦度和 10-67 GHz 的大衰减范围。该设计方法基于传统 Pi 型、T 型和分布式衰减器的频率响应特性。在 10-67 GHz 范围内，测量结果显示衰减平坦度为 6.8 dB，衰减范围为 32-42 dB。
A four-bit CMOS step attenuator is designed using a new design method to achieve improved flatness and large attenuation range from 10-67 GHz. The design method is based on the frequency-response characteristics of the conventional Pi-, T-, and distributed attenuators. Over 10-67 GHz, the measured results exhibit attenuation flatness of 6.8 dB and attenuation range of 32-42 dB.
