RF Engineer is a long time project of an old hat Radio Engineer. This site has gone through it up and downs, hopefully we will bring it back to life to educate a new generation of RF Engineers.
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

– A – Adjacent channel interference – Refers to interference caused by the energy from a transmitting channel spilling over into an adjacent channel. This interference can be minimized by applying filters to the transmitting and receiving ends or by simply using non-adjacent frequency channels within a cell. Cellular systems typically transmit on non-adjacent
Peregrine Semiconductor Acquires Arctic Sand Technologies
Peregrine Semiconductor Acquires Arctic Sand Technologies By March 21, 2017 Peregrine Semiconductor, a Murata company and the founder of RF Silicon on Insulator, has recently announced its acquisition of Arctic Sand Technologies, an MIT spin-off that designs and manufactures low-power semiconductors for use in DC-DC power conversion applications. This strategic acquisition is designed to help
