hi, I want to make a amplifier simulation in ads. How amplifiers are selected on out put power bases. Suppose i select AFT09MS015NT1. Can i get 15 watts 136--174 as mentioned in datasheet, If the amplifier is properly matched. Regards
Hi all, I have a self-designed amplifier and need to find a load line to get higher output power. I use ads for simulation. Does anyone have an example or know how to start? Thanks, Find max. Id/Ic and Vcc/Vdd from data sheet and draw a straight line between Idmax and 2Vdd on a scaled chart.This is your Load
Hi all I want to design a on chip transformer with center tap to for PA input and output match and center tap used for bias supply . But the ads mom designed transformer (SP_black block)used for bias supply in cadence simulation ,My main power amplifier device was not operating in the right quiescent point. (...)
Hi! I want to design a power amplifier and I know one of the simulations which should be run is HB simulation. I have started with the test circuit of the transistor. after finishing this step I tried to run HB- simulation. But for some reasons it couldn't be converged. I don't know exactly what is the (...)
Hi! I want to design a push-pull power amplifier in AB class. I tried to use the test circuit of the transistor in the datasheet to get some idea about designing. I'm using ads and I draw the schematic of the test circuit.now I think I should run HB-simulation. But I couldn't manage to run that. but it couldn't be (...)
What does it mean, you can't display PAE, do you see some power contours, do you got errors? Maybe specify the template you're using or make a screeshot of your schematic.
Hi all, according to Qorvo's datasheet, this device: TQP7M9103 works from 500 MHz to 4000 MHz. I have downloaded and simulated the S-parameters, and found that I can still get > 12 dB gain up to nearly 6 GHz. So my question is, what kind of limitations would I expect driving this thing beyond 4 GHz? Is P1dB likely to suffer, and if so, w
Hi I want to design a class AB power amplifier and I use spice model of D2201UK transistor (semelab) for simulation in ads, design guide>amplifier>DC and Bias point>FET_IV_Gm_powerCalc. but when I put my spice model instead of the default transistor, it doesn't work good. I am using (...)
So, you know well the Optimum Load information but you didn't do any Source Pull simulation at this power level ??? The amplifier will surely fail because high power input impedance can-probably will- be quite different than small signal one.This is very common for power amplifiers.For (...)
can anyone provide me a full example for CLASS-E amplifier wit all results using transistor in AGILENT ads. I am getting a problerm in harmonic simulation for finding gain, PAE and power
In ads can you tell me in class-E power amplifier, please refer to circuit at point 'A' in Figure at o/p port, How can I plot current and voltage waveform w.r.t to Frequency? please find attached figure.112943. 112943
Hi I am working on class-E power amplifier by using transistor as ATF52189 and i want to know how to get same s-parameter at o/p port mainly(S21) value. and how to check voltages and current at different nodes at point 'A' in image, if we apply voltage source at drain and gate? figure is attached please refer? Hope for a reply.
hello everyone could anyone help me designing a power amplifier on hfss im new on the program so i have a limited information thanks in advance
hi, I want to know the steps involved stabilizing the ldmos based amplifiers. I am using MRFE6S9125NR1. Somehow i was able to get 50 to 70 watts from 925 to 960MHz. But there is some stability issue in 880 to 915 band. ads LSSP simulation shows that that amplifiers becomes unstable at 33dbm input (...)
Hello, I am Designing a power amplifier, The transistor selected is a freescale transistor (MRF6V2300N), luckily I have found its ads design model, i have included it according to a tutorial, but while simulating it is giving following error.... Kindly guide how to correct this error?? any help is appreciated!! Thanks. [SIZE
When you do HB simulation in ads for amplifier or oscillator and it shows very high dBm at 0Hz ( in the spectral plot) along with the others, what does it mean?
Hi everyone. I want to design a power amplifier and I need a ams CMOS C-35(nmos MN1) for my design,but I can't find it in ads library.what should I do?
Hi everybody, where can I find ads simulation files of this Application note? Thanks in Advance Saeed
Hi all, I am designing a RF power amplifier for my final project. The PA adapted Doherty architecture. I intend to design it for input power of 25 dBm (which is 0.316 W). If the input signal is a sinusoidal signal, how much is the peak voltage? The 25 dBm, can I consider it as a RMS value and using P = Vrms^2 / R formula? I look (...)
Dear all, Hi. I simulate a MMIC RF power amplifier (PA) in ads (advanced design system), s-param simulation is working well but harmonic balance not. Increasing the input signal power of the PA, the output signal power increases unconditionaly, even more then DC power (...)
