Anyone knows what other books should I read to design an ultrawideband low noise amplifier? I have Microwave Circuit Design by Vendelin, Pavio and Rohde and High Frequency Techniques by Joseph F. White with me.
i have done in the past some large band amplifier
and i have seen that feedback amplifier are the best.
Usually it's preferible to use low loss components, so inductance (for example inductance emitter degeneration) or transformer (emitter out /base input) for getting also good
noise figure performances.
U can add also an indutance series resistor shunt out/shunt input feedback (for example collector/base) for improving stability and flatting gain on large band.
If u don't need low noise figure u can use a very large gain transistor and use resistor emitter degeneration and resistor collector/base feedback for getting very large band amplifier, with very flat gain and also very easy matching input/output networks.
about designing LNA broad band i can advise you to read
some articols from Microwave&RF journal .
you can find those in past issues.
website is https://www.mwrf.com/
you can find a very intersting series of articles about design wide band in past issues of july 2004 , october 2004 , november 2004, decmber 2004
Thanks. I just got an ebook version of Broadband Microwave Amplifiers from Artech House. About the articles in the past issues of Microwaves & RF, is the articles by Joseph F. White? If it is, then I think all articles he wrote is in his book: High Frequency Techniques An Introduction to RF and Microwave Engineering. Now I think it's time to read all the materials that I have as a start. Thank you.
