Abstract
Integrated Power Amplifier (PA) and filter which is part of important component for Radio Frequency (RF) transmitter is designed using Adavance Design Simulation (ADS). The main aims of the design is to provide linear amplifier and filter at the center frequency of 2 GHz and biased at the conditions of class AB. GaAs transistor is used as an active device due to ability in operating at high frequencies and can generate signals with lesser noise. Linearity of the integragted design was simulated with two tone test and the intermodulation products (OIP3) value resulted to be 50 dBm. ACPR of -50.86 dBC with 10MHz frequency spacing is achieved using the Butterworth Bandpass Filter. On the other side, high linearity will lead to more efficient transmission of the signals.
