Hi,
first you need to know a few things.
1) do you want voltage gain or power gain? 2) what is the source impedance coming from the PLL? for example, 50 ohm. 3) what is your load impedance?
Power is V2/R. If you don't want power gain, you can still get voltage gain by changing R. This is the matching network approach. When you design your matching network, you will need to use a low-pass filter configuration. However, the matching network voltage gain will be limited by the source and load impedance since the input power must be equal to the output power. Therefore, you may not be able to do the matching network approach anyway.
If you describe your application, you will get a better answer. For example, is your PLL on the same die as your design? Where is it used (a mixer for example)?
regards, Aaron
