[SOLVED] Designing Low Noise Amplifier

[Nornabila Md Nor]

Hello...i want asking about designing LNA.How can we combine matching circuit with voltage divider biasing?Kindly please answer my question because i really do not know how to combine it..Thank you

You do not say what frequency this LNA is going to work at. If its RF, isolate the voltage divider resistors with an RFC.

This LNA design for frequency 4GHZ by using transistor ATF54143 Avago Technologies.Is it relevant use voltage divider as biasing for 4GHz??

Thank you for help.This low noise amplifier at 4GHz successfully design and testing.Finally,my final year project achieve the target.
