It distributes power to the various boards/components in an SDR. Some important parameters for an SDR power supply are input voltage range, output voltage range, output ripple voltage, accuracy, load/current, efficiency, temperature, size, and required protections.
Simply put, software defined radio (SDR) is the term used to describe radio technology where some or all of the wireless physical layer functions are software defined. To understand this, consider the high level functional model of a radio presented in Figure 1.1.
An SDR consists of a radio front end and digital back end. The SDR’s radio front-end contains the receive (Rx) and transmit (Tx) functions to receive and transmit signals over a wide bandwidth; this is also what the antenna is connected to. State-of-the-art modern SDR systems cover an ultra-wide frequency spectrum.
In an SDR, signal processing is mainly implemented by means of software in a general-purpose computer or reconfigurable embedded system. Hence in principle, based merely on the software used, an SDR can transmit and receive practically any radio protocols or signal waveforms. An SDR consists of a radio front end and digital back end.
