LNA Competition

My ultra low noise amplifier (LNA) was measured yesterday.
Because the LNA was operated at 2.4 GHz ISM band, it had to be measured in our chamber to avoid other interference especially WiFi equipment.

The measured noise figure was below 0.75 dB. However, the small-signal gain is not enough to catch the Spec. And a serious problem is that the LNA is not always stable.
It means that I have a lot of works to do. I want to re-design a whole new one on FR-4 substrate.
I really enjoy doing my researches and my works.
I can't just leave my toys down. XD



* The Truth: NF = 0.62 dB, Gain : 14.05 dB




I need more time. I need more confidence.
I need work hard. I need study hard.


If I have enough time ........
If I spend less time surfing ......



I think I have a conclusion in this dark midnight.
