## How to display the spectrum of power amplifier in ADS (technology TSMC 180 nm)

Hi hanen88, The output frequency spectrum of the UWB amplifier is a windowed Fast Fourier Transform (FFT) of the output signal. The spectrum will show the frequency outputs as peaks at the frequency with the power contained at each frequency. T

## Matching network of power amplifier design in cadence

Hello, I am designing a power amplifier in cadence, but I don't know how to design matching network in cadence. I found that some papers solve this by hand calculating but deviation of this method is too large. I'd like to know whether I can design the matching network in cadence like in the ads ? (I don't have the pdk document which is (...)

## 15 Watt RF Power Amplifier Selection 140-170 MHz

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

## dc loadline power amplifier

hello everyone, i need some help to bias my power transistor. the datasheet says vgs (-10,3) vds(0,100) and maximum drain current 1.4A.. proposed voltage vds 28v which must be the start and the end point of my dc loadline? i use ads and my problem is that if the end point is vds 100v then the loadline have areas th

## ADS load impedance matching for oscillator?

Load Pull can be used, no doubt. If you consider the oscillator as an power amplifier, the principal is almost same,so max. power at the right impedance. But.. Load Impedance is also quite deterministic on other specifications of the oscillator such as Phase Noise,Drift and Pulling effect.If you would obtain max. power from (...)

## DC load line of amplifier

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

## PA transformer center tap supply (on chip)

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. Please (...)

## DC power consumption in Class-E power amplifier design using ADS

I am trying to design a class-E power amplifier using ads and using ideal elements (not transmission lines at this step), I have 2.8W DC power consumption while PAE is only 48%. The equation I use for DC power consumption is (...)

## HB- Simulation in ADS

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 source of these errors. sometimes it complain

## HB- Simulation in ADS

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 converged due to some (...)

## How we can use Load pull technique in ADS to enhance the PAE of Power amplifier

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.

## How we can use Load pull technique in ADS to enhance the PAE of Power amplifier

Hi; I ask how can i use the template of 'load pull technique ' in ads to display the PAE of my amplifier . In fact, i design an amplifier class AB and now i shoud enhance the efficiency so i should use the load pull technique in ads . However, when i use the template(design guide-->load pull) after that i delete the (...)

## Design of RF Power Amplifier

1) select a device according to operating frequency, gain, supply voltage, power and etc. 2) plot DC characteristics and determine DC operating by using Prms = Vds x Ids. Prms is RF output power. 3) do impedance matching for the PA using commercially available matching tools (e.g ads and etc). make sure the matching network within the Qmax (...)

## DIY boombox design

Consider bi-amping your speaker system. Split the sound spectrum with a crossover, then amplify. You need twice as many amplifiers, but each uses less power. Your total power usage is lower.

## RF Power Amplifier Frequency Limitation

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

## 60GHz power amplifier design flow

Simulate your passive structures in Momentum and then use the resultant S-parameter in Cadence. If your PA is strongly nonlinear (which I doubt for a 60GHz PA), it's better to extract the lumped model of your passive circuits in the 60 GHz band from simulated S-parameters of Momentum and then use these models in Cadence. But I think for the power l

## Installing a Power Amplifier in ADS

Hi. I want to use a power amplifier and a low noise amplifier in my schematic in ads. I have downloaded a design kit for required LNA from Modelithics and installed it easily in ads library , but I do not know how to install a specific PA in ads. From mini-circuit I have just downloaded (...)
