I have designed the lna on ads and practically implemented it too on Roger 5880 at 5.5GHz...I want to design a mixer that follows this amplifier using ads.Can anybody guide me?
ATF34143 is an lna (Low Noise Amplifier), and by definition any lna should work in Class-A. So, good PAE (Power Added Efficiency) is not the main target of performances of this transistor. For best performances follow the Avago application notes 1190 and 1191.
hey, i am using ATF34143 for 2 stage broadband lna and i got good result with gain, noise figure and return loss i.e. s11 and s22. But i have designed with ideal component inductor and capacitor, i want to replace it with vendor's component. As i am using ads 2009 software for it, they provide muruta manufacturing capacitors and inductor. Here

Hi, Im designing a lna using ads. I have designed my single stub matching network and I use short circuit stubs in my design. I am getting a negative gain and I m confused about this. If anyone can help on this it will be a great help.
There is a OIPn measurment block in s-parameters simulation palette,use it with low driving level at least 20dB lower than P1dB.Then extract the Gain of your lna from this value.
how to find gain error and phase error of balun-lna in ads. By doing s-parameters simulation.If you balun has 3 ports, check db(S(3,1)) and dB(S(2,1)) for gain imbalancing and phase(S(3,1)) and phase(S(2,1)) for phase imbalancing.
Hello guys, I am designing an lna and would like to match it for a nearly optimum noise condition. I´m running in trouble trying to design the input matching network, which should convert a 50 ohm source to my desired source impedance (let´s say 10 + j*10 Ohms). So far the matching tools that I´ve been using (including the ads Impedance matc

Hi, Can anyone help me out with plotting gain Vs frequency for lna using ads ,other than with S parameter analysis(S21)
lna is showing same output what ever the input it has, it is not showing amplifying signal. Some lna is showing negative gain, when -500mV appeared at the gate. I think your lna is oscillating, at a frequency that you are not looking for...

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
hai to all, can we tune the parameters of lna in cadence spectre like we doing in ads???

I want to create a plot of NFmin vs Vgs in ads 2009........But by default the x axis is having frequency as the independent do i make Vgs as the independent variable?............
ads ships with everything you need. Just open a new schematic and select Insert > Template... then select and place the HB2ToneSwptPwr template. Drop your lna into the schematic (with necessary voltage sources) and set values for RFfreq, fspacing and in the Sweep Plan set the input source power parameters. The resulting data display includes pre

Hi, I need some presentations or details about RF CMOS technology in general. Is there any ready reference which I can download? Also, if somebody has tutorial presentation on RFCMOS based lna design using ads...that would be great as well. Cheers
how to simulate IIP3 for lna circuit in ads.....? :???:
I learn that K=(1-|s11|?-|s22|?+|Δ|?)/(2|s21||s12|)>1 and|Δ|>1 then lna or PA will be stable. is there any software can simulate and calculate the K? can i use a network analyzer to test a lna or PA'K factor?or there is other way? thanks for any advice
Hi, can any one help how to design a lna using ads? How to theoretically calculate the Single ended lna and how to design it on ads
You can access new published desigs through IEEE. Also if you just use google you will get more information about lna designs with CMOS technology. For example:
Hi I'm designing lna in x-band and I simulate the layout in Momentum and FEM simulation and I found a big different between the simulated results and I think the problem that there is shifting the operating frequency to the lower frequencies. Please help me... in which simulation results I can believe??? below you can see the attached simulated
IF you want to fabricate lna on PCB then there are good transistors available in market. For example BFR 92 or 92A, I am not sure about Cadence because I never used it. but in ads libraries are available. If not make your own model. Or buy ready made lna chips from mini-circuits.
If I understand your intent correctly, simply make two circuits on your schematic. The first circuit will have the lna all by itself (with a proper signal source and load connected). Circuit two would be a copy-paste of the lna circuit with your bandpass filter connected, then terminated into a proper load. Set up net names like lna_Vout (...)
If a resistor have more reactive parasitics (as capacitance or inductance), there is a possibility the input match of the lna to move closer to gamma optimum, and get lower NF.
Hello I have designed an lna in ads and i made the layout in order to perform the cosimulation. But results are grossly different (for example in circuit simulation the noise figure is 0.4dB while in the co simulation it tends to be 40dB and more). I suspect that i have made a serious mistake in setting up the co simulation. I followed the procedu
