I have a new project that will use one of these surface mount GSM-GPRS Modem Module.
The RF antenna connector is not on the module itself and need to be solderer of the Main PCB
connector:**broken link removed**
the distance between the module edge and the connector will be max 5mm(0.2").
This would be the only controlled impedance track on the entire pcb.
I really don't want to have to specify a specific material, stack-up... just for 5mm of RF tack.
The PCB specifications must be as loose as possible to reduce costs.
Does 5mm of RF track at gsm frequency ( around 900MHz), absolute need controlled impedance? or would a loose approximation of the track impedance sufficient for 5mm?
thanks
