Hi all.
I'm working on a bluetooth design. The bluetooth chip rf out goes through a few passives (filtering and impedance matching) and then almost straight to the antenna. the track length to the antenna is only about 5mm. Is it necessary to design a 50ohm trace for such a short distance(relative to the wavelength).
I can understand if the track length is a significant portion of a wavelength , but at less than 5% does it make any real difference?
Cheers
Rob
