In this letter we present a new design of a microstrip microwave PA (power amplifier) for PCS (Personal communication Services/System) applications at 1.85GHz and it is based on AT-41410 NPN transistor that has a high transition frequency of 10GHz. The design process apply in this work is obtained by ADS (Advanced Design System) software. The simulation results show good performances in terms of small and large-signal. The proposed amplifier design achieves a high gain in excess of 12.8dB. For the input reflection coefficient (S11) is below than -33.7dB. Regarding the output reflection coefficient (S22) is below than -29dB. Thus, the unilateral transmission (S12) is less than -19.5dB and for the output power is rise up of 18dBm at 1dB compression point.
