Q: Impedance Matching Network with tracks+connectors in between (practice)

emeceI've been struggling on how to design (and develop in practice) an impedance matching network with some traces/tracks/paths (whatever you wanna call it) and some connectors in between. So here is the architecture: Antenna (50 Ohm) + path (50 Ohm) + Matching network + path & SMA connector (?) + S...
