The objective of this project is to design a power amplifier for a new two way mobile radio product being launched by Motorola. Two-way mobile radio consists of a transmitter, receiver and a voltage-controlled oscillator. Mobile radios usually have transmitter whose power output ranges from 1 W to 50 W. Design of transmitter lineup for mobile radio involves the design of appropriate matching network for driver and power amplifier. The power and voltage control of these devices are equally important. Designing a mobile radio transmitter is regarded tricky due to difficulty in getting a robust transmitter that is stable with minimum oscillation. In this work, the design is attempted usmg Advanced Design Simulator (ADS). The design simulation provides accurate simulation on harmonic filter and antenna switch. 50 ohm matching networks have also been designed and simulated using ADS and it gives close approximation to the specifications. The radio has since been prototyped and tested. The evaluation and testing of the radio has been carried out and it satisfies the specifications that are set by the Telecommunication Industry Association (TIA). Some minor optimization has also been performed to improve the radio performance. Eventual product is a transmitter line up that function well today. 111
