What software for design and simulation RF LNA, fileten etc?

[Astrid]

I kinda lost track of design software for simulation of RF circuits.
Eamples of use
- Design of LNA (amplifier with ATF-54143 for the frequency x)
- Filter design (tape or standard)
- Design of antennas

I would like it to be not only simulation software, for example, but he could also propose a filter to specify the type, order, and frequency.

I know that there
- Agilent ADS
- ANSYS HFFS
- Awr Microwave office
- CST Studio

What would from that recommended the possible something else?

Agilent ADS and Microwave Office are enough for RF circuits but others ( HFSS and CST) are more convenient for real and electrically large EM 3D structures.
