Dear Friends.
I am Shahrukh Saleem from Pakistan. I am a SCADA Engineer working on EMS. Recently I have come across a faulty GPS Antenna. I pulled out the pcb from the antenna housing and looking upon the components. Please have a look on the attached snapshot of PCB. I have recognized the Resistors, Inductor, Capacitors and Transistors, but I could not recognize the component labelled SGT 1575c. I know that GPS mean frequency is 1575.42 Mhz so this component deals with the frequency. Is it a band pass filter? Please help me on understanding the circuit. Also please some one explain the working of this circuit. Thank you.
Regards
