Dennis G. Hall is a licensed amateur radio operator and a professor emeritus at Vanderbilt University. An old joke asks: what washes up onto tiny beaches? The answer is microwaves. In truth, we are ...

Time and frequency standards are a key part of technologies we have come to rely on in our daily lives, from GPS navigation and cellphone networks to the electrical power grid. The importance of these ...

The project aims to build a simple and easily-reproducible RF/Microwave frequency counter that is based around a PIC16F876A microcontroller. This particular frequency counter has three inputs ...

It is an age-old problem. You have a 2.5 GHz source and you want it at 5 GHz. You need a frequency doubler. [All Electronics Channel] has an interesting video that talks not only about the theory of ...

For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment TOKYO--(BUSINESS WIRE)--NTT Corporation (NTT) and ...

Optical frequency combs can link frequencies in the microwave domain to high-purity laser emissions, yielding unprecedented precision in time-keeping and metrology. Now scientists have generated ...

Researchers have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the stability of microwave signals 100-fold. This marks a giant ...

The detection process relies on a microwave cavity made of copper that is immersed in a strong magnetic field. According to the theory of axion-photon coupling, axions interacting with virtual photons ...
