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 […]

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 […]

6 Things Strong Leaders Do That Weak Leaders Do Not

SpaceX just checked off another item on its bucket list on Thursday night. At just after 6:20 p.m. EDT, the private spaceflight company successfully launched a Falcon 9 rocket with a first stage that had previously flown before.* As an added bonus, SpaceX returned it to Earth, landing it upright on a drone ship in […]
