Can we write this for a certain block like lna ? Yes, there is a relationship between Gain and the Scattering Parameters of an amplifier. IF yes, where is it coming from ? Where is what coming from? There are derivations in Pozar's microwave Engineering, Chapter 11
I am doing project on design of lna (2 , 4 , 6 GHz). I am using NE76084 transistor manufactured by NEC corp. (formerly NEC corp.). I using the non linear model of the transistor in AWR microwave office environment. I can not completed the input matching and output matching circuits using lumped element
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..
I am doing project on design of lna (12 GHz). I am using NE3210S01 transistor manufactured by Renesas corp. (formerly NEC corp.). I using the non linear model of the transistor in AWR microwave office environment. I have completed the input matching and output matching circuits using lumped element for gain=12 dB and NF=0.7 dB. After that i want to
In most of the cases low power transistors are not multi-emitter, and they use two emitter pins on the package just to allow better PCB design at high frequencies. For example when design lna's working at microwave frequencies and need to use emitter degeneration inductor, or to decouple the emitter on both sides of the package. In these situations
I kinda lost track of design software for simulation of RF circuits. Eamples of use - Design of lna (amplifier with ATF-54143 for the frequency x) - Filter design (tape or standard) - Design of antennas I would like it to be not only simulation software, for example, but he could also propose a filter to specify the type, order, and frequenc
When you look at the equations for Noise one of the Biggest contributors is Bandwidth. Also it is easier to get better performance out of an Amplifier in a narrow bandwidth. Go look at the Frequency response of Caps and Inductors, and even frequency response of microwave transmission line. Then find out what is the dimensions of Zo for your PCB
you must see some examples on microwave transistor amplifiers design and analysis,Gonzalez but first you must check your transistor is stable or not then matching
Dear Sir, I need to design lna ckt, for that need biasing ckt for the ATF 54143 and ATF 34143 transistor, If any body know how to bias the RF and microwave circuit, please give me link.
HI, btv, There should be in the book called "microwave technologies basis" or some books related to Smith Chart. You can also search in the Internet to get how to design lna, and there are many exapmles on the net. Good luck.
Dear sir, I want to start the design of single stage microwave low noise amplifier design,if any body is having MWO files regarding on How to start to design of lna . Please send me.
As thylacine1975 said, that's pretty generic. It is more or less a basic diagram for every single microwave amplifier, so there is not much else to say unless you provide more data.
Hello I am building this and I would like to have a phantom supply for the lna (supply voltage through the same rf coaxial cable). Is my configuration of the DC blocks and the Tee adapters correct? I am wondering about the Tee adapters losses as well as the DC blocks power handling capability.

Hello, I am simulating a lna at 5ghz. I have 2 questions here. Firstly, while importing s-parameter data file for a HEMT transistor, the S-param data is from 100mhz - 20 ghz and noise data is from 2 - 18 ghz? why ? Because while simulating it gives the message like illegal noise parameters. Secondly, here to stabilize the amplifer, I hav
you can check microwave transistor amplifier design by is great
Dear roommates I'm going to design some Γs plane I plotted the values of Γs that produce the desired noise figure and gain.I'm going to find the mapping of the point in Γs where both noise figure and gain is satisfied in ΓL plane to check for stability. would you please help me with introducing some function in microwav
Hi! I am currently designing microwave low noise amplifier. We are going to fabricate the lnas. However, we have yet to design the radial stub and the tee junctions. Can someone tell me the things to consider in designing the tee junction. Thanks a lot.
