Many of today’s GPS receiver LNA designs are based on discrete transis-tors rather than MMICs, primarily because designs using discrete transistors result in amplifiers with lower noise figure (NF). However, for today’s portable applications, where compact circuits and extremely quick time-to-market are both requirements, circuits with discrete transis-tors may no longer be the best design choices.
