RF output matched at 830 MHz
Determine L and C according to the frequency and the RF port’s S parameter.
High-pass type output matching is used.
Determine whether or not to attach an input matching circuit according to the impedance of the previous stage.

RF output matched at 1.9 GHz
Determine L and C according to the frequency (including the strip line length on the mounting board) and the RF port’s S
parameter.
Low-pass type output matching is used.
Determine whether or not to attach an input matching circuit according to the impedance of the previous stage.
If the conversion gain is too low, implementing a parallel configuration of two chip capacitors for C can lower the Q value.
