High Performance v-Band Gaas Low Noise Amplifier With Modified Coplanar Waveguide Ebg Transmission Lines Technology

Abstract

Abstract-This paper presents an integrated millimeter-wave (mmW) low noise amplifier (LNA) which is implemented by using 0.15-µm baseline GaAs pHEMT technology. The design utilized modified co-planar waveguide (CPW) to perform a slow wave transmission line (TLine) with electromagnetic band gap (EBG) ground structures for the input/output matching networks. The low noise V-band LNA chip size was hence reduced by adopting the new EBG transmission lines. The developed amplifier exhibited a noise figure of 6.21 dB, and a peak gain of 17.3 dB at 66 GHz. Additionally, the amplifier has linear characteristics and its measured third-order intercept (IIP3) point is greater than −0.5 dBm under a dc power consumption of 75 mW.
