Radio frequency system architecture and design pdf
Radio-frequency engineering - WikipediaIt is incorporated into almost everything that transmits or receives a radio wave , which includes, but is not limited to, mobile phones , radios , Wi-Fi , and two-way radios. RF engineering is a highly specialized field that typically includes the following areas of expertise:. To produce quality results, the RF engineer needs an in-depth knowledge of mathematics , physics and general electronics theory as well as specialized training in areas such as wave propagation, impedance transformations, filters and microstrip printed circuit board design. Radio electronics is concerned with electronic circuits which receive or transmit radio signals. Typically, such circuits must operate at radio frequency and power levels, which imposes special constraints on their design. These constraints increase in their importance with higher frequencies. At microwave frequencies, the reactance of signal traces becomes a crucial part of the physical layout of the circuit.
Basics of Designing a Digital Radio Receiver (Radio 101)
This paper introduces the basics of designing a digital radio receiver. With many new advances in data converter and radio technology, complex receiver design has been greatly simplified. This paper attempts to explain how to calculate sensitivity and selectivity of such a receiver. It is not by any means an exhaustive exposition, but is instead a primer on many of the techniques and calculations involved in such designs. Many advances in radio design and architecture are now allowing for rapid changes in the field of radio design.
As they are integrated on a single substrate, SoCs consume much less power and take up much less area than multi-chip designs with equivalent functionality. Because of this, SoCs are very common in the mobile computing such as in Smartphones and edge computing markets. Systems on Chip are in contrast to the common traditional motherboard -based PC architecture , which separates components based on function and connects them through a central interfacing circuit board. A SoC will typically integrate a CPU, graphics and memory interfaces, [nb 3] hard-disk and USB connectivity, [nb 4] random-access and read-only memories and secondary storage on a single circuit die, whereas a motherboard would connect these modules as discrete components or expansion cards. More tightly integrated computer system designs improve performance and reduce power consumption as well as semiconductor die area needed for an equivalent design composed of discrete modules, at the cost of reduced replaceability of components.
