Abstract: Software Defined Radio plays vital role in many applications as the components in it are software selectable. We can select desired frequency and modulation technique which can be selected through software. The desired frequency selected should be locked in phase locked loop (PLL). The desired frequency is selected by giving commands from Graphical User Interface (GUI) using Universal Asynchronous Receiver Transmitter (UART) and Serial Peripheral Interface (SPI) protocols.GUI is created using Qt creator which is a cross platform C++ and java script Integrated Development Environment (IDE). GUI is designed to generate the desired frequency. As soon as we select a frequency, the corresponding address and data are generated to configure in the Radio Frequency (RF) transceiver. These address and data are first sent to the PIC microcontroller by communicating through UART protocol and after setting data format, these are sent from Peripheral Interface Controller (PIC) to RF transceiver by communicating through SPI protocol. With this process, the registers in RF transceiver are controlled by the user
