Why the Impedance Matching in RF Design is always 50 ohms?

Why the Impedance Matching in RF Design is always 50 ohms?

Why is it that in many Radio Frequency systems and components, most of the time the impedance is 50 ohms? ( Sometimes this value is even the default value for the  PCB board). Why not 60 ohms or 70 ohms? How is the value is determined? What`s the meaning

SWR AND RETURN LOSS : DO THEY REPRESENT THE SAME THING?

SWR AND RETURN LOSS : DO THEY REPRESENT THE SAME THING?

Good impedance matching is required for the efficient transfer of signals between connected devices. Unfortunately a perfect match is rarely achieved. There are two common ways to express a device’s impedance mismatch: Return Loss and Standing-Wave Ratio

HOW TO MEASURE NOISE FIGURE BY SPECTRUM ANALYZER AND A NOISE SOURCE

HOW TO MEASURE NOISE FIGURE BY SPECTRUM ANALYZER AND A NOISE SOURCE

Noise figure is an important parameter in many RF applications. Per its definition, Noise Figure (NF) is a measurement of the degradation of the signal-to-noise ratio (SNR) which is caused by components in a signal path. It is a number by which the perfor
