hello, I am working with a Itrax02/08 gps module. In the datasheet it states that you have to add a 50 ohm pcb trace for the antenna connection. However i am planing to use a antenna connector that already has a 50 ohm resistance. the question is, Do i still need to make the 50 ohm trace on my pcb, or is the resistance in the connecter sufficient?
if somebody could shine a little light on why there is a need to 50 ohm resistance, and the inportence of it, that would be appriciated
