RF Low pass filter Design (matching + filtering)

[makkawi22]

hi
i'm working on PA LPF ,4W,VHF band. the PA outpout impedance is complex value and I need to connect it to an antenna with 50 ohm impedance.So, there is a need for harmonics rejection (by LPF) and for an Impedance matching network.
My questions:

1- Can I design a LPF (for matching and filtering at the same time) with as minimum as possible insertion loss?

2- Is there any good software which can help me for this design?
Thanks

1) Sure, but it also depends on your intended bandwidth, easiest would be a second-order (LC) low-pass filter.

2) You want a commercial software (ADS, AWR etc.)? Or free (e.g, **broken link removed**)
