Hi,
In my circuit, a chip antenna(ANT016008LCS2442MA2)is used in the circuit for Bluetooth low energy. Balun(HHM1711D1)is used for impedance matching and to achieve compatibility between feedline and antenna.It's recommended to connect BLE pins & balun with 100 ohm differential lines and balun & chip antenna with 50ohm differential pair. How can i match a trace for a particular impedance. I think the impedance depends most importantly on the trace width and also the thickness of the dielectric right? So I think i need to consult with the pcb fab house. Am i right? What are the parameters that i should ask them to get my PCB done as per the recommendation?
Any help would be appreciated
