Different LNA Topologies Designed with HEMT Technologies at Ka and Q Bands

Abstract

The main drawback of designing LNA with CMOS technology is the high power dissipation. This problem can be overcome by designing LNA with HEMT technology. In this paper we went through several LNA‘s designed with different HEMT technologies from the past few decades. Assessment of different LNA topologies with HEMT technologies around ka and Q band is performed in this paper along with EM simulations of PP1010 unconditionally stable LNA.
