Design and Simulation of Wideband Amplifier at Extended C Band

Communication industry is currently in continuous growth. In recent time for satellite communication spectrum at C-band is almost congested and for various new applications extended C band is being explored. In particular the Very Small Aperture Terminal [VSAT] networks have gained wide use for business and private applications. Wideband Power Amplifier [WPA] is important block in transmitter section. After Literature survey and studying different transistor, I am going to design Wideband Power Amplifier at centre frequency 6.85 GHz over 100 MHz bandwidth for Very Small Aperture terminal at extended C band. Its performance is evaluated based on certain parameters like Gain, Efficiency, P1dB, TOI and it is simulated using Advance Design System [ADS]. Accordingly, Gain 13.370 dB, Noise Figure 1.533 dB, Input return loss -29.454 dB, Output return loss -26.016 dB has been achieved using impedance matching in ADS tool.
