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

What should be paid attention to when testing P1dB?

What should be paid attention to when testing P1dB?

Non-linearity is a topic that cannot be avoided by RF active devices such as PA and LNA. Although it is inevitable, it is still hoped to keep it as low as possible to reduce the impact on the system. There are many parameters to measure nonlinear characte
