描述了一个完全的第一个示范 集成Doherty功率放大器(PA)的单片微波 后失真线性集成电路(MMIC) 毫米波(毫米波)频段。 Doherty放大器 单片,使用0.15米的GaAs HEMT的过程中,实现了小 7 dB的信号增益从38至46千兆赫,具有结构紧凑的芯片尺寸 2毫米 2 。 Doherty放大器的饱和输出功率 21.8 dBm的。 Doherty放大器之间的相似拓扑 和后失真线性化,使人们有可能改善 同时在毫米波功率放大器设计的效率和线性度。 门的主要和峰值放大器偏置优化后, 漏效率提高6%,在6 dB输出回退 的互调失真(IMD)准Doherty放大器 可以提高在42 GHz的18 dB的比较平衡 放大器的工作-Abstract— This letter describes the 狻猀琀 demonstration of a fully

integrated circuit (MMIC) with post-distortion linearization at
millimeter-wave (MMW) frequency band. The Doherty ampli旻爀
MMIC, using a 0.15- m GaAs HEMT process, achieves a small
signal gain of 7 dB from 38 to 46 GHz with a compact chip size
of 2 mm2 . The saturation output power of the Doherty ampli旻爀

ef揻椀攀渀挀礀 and linearity simultaneously in MMW PA designs.
After gate bias optimization of the main and peaking ampli旻爀,
the drain ef揻椀攀渀挀礀 improved 6 at 6-dB output back-off and
the inter-modulation distortion (IMD) of quasi Doherty ampli旻爀
can be improved 18 dB at 42 GHz compared with the balanced
