How to increase high frequency output power
Can you maybe elaborate on what you mean by "high frequency output power"? If you are referring to higher power at high frequency, then inductive peaking will not help (and of course you won't get flat response with ideal inductors. Putting in a finite quality factor will improve the 'frequency range' but I am still confused how does it relate to power)
For example in the below case
It depends on many variables.It's not easy to say..
Output Power may be function of Power Gain, Load,Transistor (Amplifier/Active Device ) itself,Matching,Parasitic Elements,Package, etc.
If I think that practically, it seems to me a "Mismatch Effect" but it might also be another thing..Hard to say..
Can this be solved by impedance matching? Normally that is associated with the goal to maximize power transfer.
Input arrives as a combination of voltage and current. The matching network raises voltage and reduces current (or the other way around). Values are selected so that the outgoing signal drives the next stage in the most efficient manner.
A passive network might consist of one or more LC arrangements.
The curve that circuitking has shared shows a very wide region of operation. Obtaining matching across such a wide range is quiet difficult. Typically, it would require the matching circuits to be tuned for different frequencies.
Is it just one PA or there are multiple PAs operating at different frequencies? Can you share the source of this image?
