Output of a printed circuit board

Hi How can one explain the presence of too much noise in the output of a high frequency PCB output? How can I reduce the noise? thanks

A bit like asking why it is so noisy where you live and how could you reduce the noise. eg there are countless causes of noise - both generated internally and entering from the environment. More details would be needed to give any meaninful advice.

You would need to give far, far more details of what the PCB does, what the output is and what the nature of the noise is.

Noise reduction consists typically of stopping external ambient noise getting in eg by screening. It also consists of designing for lower impedance and/or lower temperature to reduce the generation of thermal noise. As an alternative to reducing the amount of noise generated, you can filter soem out out by limiting the bandwidth of the system. Or use any combination of all three.
