In this paper, a Si-LDMOS Doherty power amplifier using 2.620 to 2.690 GHz band is presented. The fundamental objective of the proposed Doherty amplifier technique is to principally advance the efficiency of the transmitter while high linearity is maintained. This research focused on comparing performances between the double stage power amplifier and the conventional single stage class AB power amplifier. Consequently, individual simulation was conducted for both amplifiers. The results have shown that proposed double stage Doherty technique provides PAE of 52% and P_out of 41.5 dtechnique provides PAE of 52%Bm as against 28% PAE of single stage class AB PA. However, the performance of the double stage Doherty has demonstrated an impressive improvement by 24% power added efficiency.
