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

Two definitions of phase noise and brief description of test methods

Two definitions of phase noise and brief description of test methods

Phase noise is a very important radio frequency index. In a communication system, phase noise will affect the vector modulation error of the vector modulation signal and worsen the bit error rate. In radar applications, phase noise will affect the radar's
