FHX76LP LNA matching network

时间:04-05 整理:3721RD 点击:
Hi,

I need to match the LNA FHX76LP to 50 ohms ,

my freq of operation is 9 to 10GHz (need to match the LNA from 9GHz to 10GHz)

Has anyone done matching with this amplifier before ?

if so kindly provide me with the matching circuit or Any papers that can help me match the component !

At that frequency you must do "Noise Matching" and you have to know Noise parameters of this transistor to do that.
For Noise matching, you should read some textbooks and maybe some Application Notes.

FHX76LP is one of the best Noise Figure high-frequency transistor on the market.
The datasheet provide all the information to design a low noise figure amplifier for frequencies up to 20GHz (Γ opt, Rn/50, etc).

Is designing a Matching network at 10 GHz using micro strip line possible ?

Or is there any other way to match the impedance ?

You can't use anyway lumped elements at that frequency.You will use Microstripline techniques..
