I have done the circuit design of GPS module.
I have taken the U-blox NEO-M8U and GPS Internal active antenna JCN04N to design the GPS.
I want to know how to do impedance matching with GPS module and antenna.
Please somebody help me to solve this problem.
Thanks, advance.
Question is where you got the values for C83 and L17 bias T? C83 seems a bit low capacitance. L17 has self resonance around 1 GHz, hopefully still sufficient impedance at GPS frequency.
