I have completed design of my LNA at 2.1 and 4.6GHz. Thanks to edaboard members for your help.
Now I am checking port parameter(s11, s21, s22) with help of Agilent's VNA.
But i am not getting notches at desired frequencies.
s11 is better at 1.6GHz and s22 is better at 1.2 and 1.6GHz.
Hi to everyone.
This is my first post on this group.
Can anyone clear the following doubts.
I am designing MSA for GSM 900/1800.
I want to know, how we can calculate feed line dimesion.
And simulation result shows negative gain, what it indicates?
How to increase surface current on...
I am designing LNA at 2.4GHz using ATF541432a. I have designed matching circuitary on input and output side.
Now i am left with Bias Circuit design.
How can i calculate values of L(for RF block) and C(to block DC)?
And if i do voltage divider circuitary then will it affect noise performance of...
i am designing a lna using Avago's transistors using Microwave office AWR.
Doing a simulation using s2p file.
i hav 4 file with different Id and Vd values and using one of them at Vd=3v and Id=40mA.
but not getting proper I-V curve.
........Please anybody help me out that..
