Thickness from microstrip to ground plane is 3 mil. Trace thickness is 1.8 mil. Trace width is 4.9 mil. Dielectric constant is 4.

It says the impedance is 51 Ohms. Am I missing something?
Why would some of the layouts compromise the match with a...
Hello,
I am designing a RF PCB with a WiFi module. The trace thickness of the antenna feed is 4.9 mils for 50ohm impedance. This signal width is thin compared to the matching component pads (ie 0402 size) and edge SMA center diameter pads. Many of the layouts I've seen for RF boards define a...
I am designing a PCB for a bluetooth/wifi chip that has different RF input pins for the Bluetooth and Wifi. Instead of using 2 antennas and having 2 separate traces into the chip, can I use a single antenna and a coupler to split the antenna signal into two rf paths going into the chip? Are...
