I want to start research on high power amplifier design for broadband applications. Could someone let me know what would be the best starting point? I have some knowledge of NI AWR design environment.
Santosh,
Please attend two or three workshops in reputed institutions. In parallel carry out literature survey and go through popular you tube videos and all.
Read book on PA by Cripps, design guide materials from keysight and research papers.
Sir,
I would recommend you to go through a few lectures of Dr. Jayanta Mukherjee (NPTEL) study basics of MMIC/RF-CMOS design, basics of GaAs and GaN and read out from Guillermo Gonzalez (Power Amplifier) book. Check this paper as well.
There is a constraint in designing the wide band power amplifiers since the amplifying devices have a limited gain bandwidth product. In creasing the bandwidth will limit the gain if the amplifier.
It is so that one better design multi band amplifier rather than a wide band amplifier since one can optimize the amplifier operation in each band using resonant rf amplifiers.
At first you choose the transistor, then you set the operating point then you match the input source and the output load. You can use the Agilent tools ADS to help you design the amplifier. You have to take care of the stability of the amplifier.
