Next time you get a new device and excitedly unwrap its little poly-wrapped power supply, remember this: for every switch-mode power supply you plug in, an amateur radio operator sheds a tear. A noisy ...
The received power of GPS and Galileo navigation signals at the antenna output of a user receiver is typically extremely small, from approximately –165 up to –150 dBW, which makes them inherently ...
Radio frequency interference (RFI) caused by human communication techniques (e.g., satellites, base stations, and navigation radars) can significantly distort shapes of multichannel time-frequency ...
The National Radio Systems Committee recently published the results of a study on AM band noise. The report, principally authored by John Kean, is titled NRSC-R102, “Measurement of AM Band RF Noise ...
RF-to-baseband front ends consisting of a low-noise amplifier (LNA) cascaded with a mixer downconverting RF signals to baseband have become the epitome of RF devices tested in high-volume ...
Magnestar employees include (from left to right): business analyst Rex Xia; Michael O'Meara, systems and astrodynamics lead; Infrastructure Director Ian Service; and Jacqueline Good, founder and CEO.
Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing—one is the radio-frequency interference (RFI) mitigation, ...
The proliferation of wireless transceivers in portable applications has led to increased attention to an electronic circuits’ ability to operate in the vicinity of high frequency radio transmitters.
