I recently did impedance matching, and the circuit has been basically determined. I found that there are many capacitors and inductors on the market. Have you ever encountered similar problems? How is it solved?

0.5M is a very common signal, the component deviation does not have much impact, 2.4G impedance matching is difficult.

This problem can be solved in series and parallel.

If the frequency is relatively high, use distributed parameter microstrip line matching instead of lumped devices, or use distributed and lumped integrated methods to match, if it is not possible, use capacitive sensing components in series and parallel to match.
