Abstract :
A Doherty Amplifier operating at 2.4 GHz and a supply voltage of 2.5-3V is determined in this paper. The amplifier was designed in the Triquent GaAs process using the ADS software package. Simulation results show high output power and good power gain linearity up to the 3dB compression point. The results also show good 2nd and 3rd harmonic suppression.
