28 GHz Wilkinson power divider with λ/6 transmission lines in 65nm CMOS technology

This paper presents a method to design Wilkinson power divider using transmission lines less than quarter wave length. The transmission lines less than quarter wave length of Wilkinson power divider is compensated by parallel capacitors. Therefore, this is helpful to reduce circuit size and to enhance productivity. The measurement results reveal that the insertion loss is 0.82 dB at 28 GHz. The measured return loss is better than 10 dB in the whole band of interest (20–40 GHz). The Wilkinson power divider is fabricated using 65 nm 1P9M CMOS technology.
