PoC Filter Solution – SMD-POC-006
Overview
The SMD-POC-006 is for PoC applications spanning an
8 MHz to 3 GHz frequency range, injecting a current of 0.6 Amps.
The impedance measurement was generated in simulation using measured Z-Parameter files for each component.
S-Parameters were generated by taking two SMD-POC-006
boards connected by a Leoni Dacar-302 coaxial cable. Usinga DC Power supply, the DCin was connected to CON3 of thefirst board, while the DCout was connected to the CON3 of thesecond board to close the circuit. All measurements were atroom temperature and are considered typical responses forthe solution.
