Why are short connections used at microwave frequencies?
To increase neutralizing resistance
To reduce phase shift along the connection✓پاسخ درست
To increase compensating capacitance
To reduce noise figure
توضیح
A signal takes measurable time to travel along a conductor, and at microwave frequencies a wavelength is only centimetres long. A connection of even a few centimetres becomes a significant fraction of a wavelength and introduces phase shift, so connections are kept short.
