I have designed a microstrip layout of power amplifier at 2.4 GHz. The input and output matching sections have been designed in microstrip.
But my DC bias network is containing lumped components - inductors and capacitors.
I want to replace these inductors and capacitors with microstrip lines so that my complete design is in microstrip layout form.
So please help me with how to replace the lumped inductors and capacitors in my circuit with microstrip lines.

replace a capacitor toward ground with a "open ended" stub and the inductor with a narrow microstrip; after that optimize the dimensions for better performances of the PA
