How to implement a passive RLC circuit from transfer function?

I'm designing a passive filter for a power electronic circuit.

Theoretically I have obtained a transfer function of a passive filter that fits my requirement. But I don't know how to implement it practically using a RLC circuit. I searched online but most of the solutions are showing using OPAMPs. So can anyone suggest me the steps (procedures) to implement my transfer functions using RLC circuit?

My transfer functions are for instance given below.

• 20/(4.4e-06 s + 1) or 4.5455e+06/(s + 2.2727e+05)

and

• 9e-05 s/(1.08e-10 s^2 + 1)
