Question

the explain application of the stability of the phases

Answer 1

SOLUTION:

Let us here we explain about the application of the stability of the phases,

Here we can see that Phase stability in microwave cables is important in applications, where the temperature plays the main role.

so the challenge is in the RF cable industry:

PTFE, instead of having excellent dielectric properties especially at high frequencies, making it an excellent insulator,

It also shows a non-linear change in a phase when subjected to the temperature of 15-25^0C temp. range.

This behaviour, also known as the PTFE knee, it has caused several issues across major aerospace, defense and test & measurement equiment manufactures.

Let us here the phase stability is critical for more specific applications, which are phased array antennas, and where it is precisely the phase what steers the direction of the antenna's signal;

The newest body scanners which uses similar phase array technology, SAR satellites where some of the challenges explained above are present; or network analyzers, where the phase invariance over temperature is vital for providing accurate measurements.
