The main objective of this project was to clarify on the Amateur Radio Application, mainly focus on the transmitter side. Signal-to-Noise Ratio (SNR) has always been the main concern in Radio Communication; it is required to have a high SNR margin but compromisation on the cost of fabrication and vice versa. Optimization of components will be done in this project in highlight that the final product to have an optimum or balance in terms of cost of production, SNR margins and variety of input signal. For this project, it is focus on the up-conversion of the frequency mixer as well as the Class C amplifier. Radio communication transmitter works by mixing a Radio Frequency (RF) with a Carrier Frequency and the resulting signal of the mixing process is a signal that is twice the bandwidth than its original input signal. The simulation for this project will show the components that will be used later in circuit fabrication therefore; acknowledgement regarding the cost of production and the result will display the Noise and Signal configuration and from the information obtained shall be calculated for the SNR margin.
