Radio Architectures, Pt 4: sensitivity, noise, front-end amplifiers

System sensitivity and noise The noise from each component in the front end adds to the receiver’s noise floor, which sets the limit on the minimum signal level that can be detected. Noise can be characterized by its power spectral density (PSD), which is the power contained within a given bandwidth and is presented in units of

RF Basics: Radio Propagation

It is fitting in a book about wireless communication to look at the phenomena that lets us transfer information from one point to another without any physical medium—the propagation of radio waves. If you want to design an efficient radio communication system, even for operation over relatively short distances, you should understand the behavior of

Gigabit LTE: Crazy-fast wireless speeds, explained – CNET

Mobile You might have missed one of the Samsung Galaxy S8’s best features — support for Gigabit LTE. That’s because, for now, it’s still a little-known technology most phones don’t support. The good news is the carriers are doing something about it, upgrading their networks to higher speeds and more capacity, all so that episode

Real World RF Filter Design and Construction | Hackaday

We bet when [devttyS0] made his latest video about RF filter design (YouTube, embedded below), he had the old saying in mind: in theory, there’s no difference between theory and practice, but in practice, there is. He starts out pointing how now modern tools will make designing and simulating any kind of filter easy, but
