    Closed: ADS Installation Error

    Dear sir,
    Once I installed the Advanced Design System. ADS is not installed in the C drive, it is showing installer UI Mode Error. I attached below jpeg file of error message.

  11. Closed: What is the difference between characteristic impedance and normal impedance?

    What is the difference between characteristic impedance and normal impedance.
  12. Closed: Re: In which direction we need to go and read the reflection coefficient angles.

    Problem is as follows
    A 70 Ohm lossless line has s = 1.6 and reflection coefficient angle =300 degree. If the line is 0.6 lamda long, obtain (i) Reflection coefficient , Load impedance, and input...
  13. Closed: In which direction we need to go and read the reflection coefficient angles.

    I need to find reflection coefficient angle = 300 degree using Smith chart. In which direction I need to go and find the angle 300 degree. There in Smith chart, they specified 0 to ± 180 degree, how...
  14. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    Sir,
    No, it is not shorted, it seems as shorted,but it is not shorted(Different screen shots is shown, in that you can notice, there is no short)
    I have shown in the screen...
  15. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    Sir,
    I am sorry, even I connected the DC blocking capacitors 100pF on either side of meander line DC supply lines. It is showing same biasing as same earlier, it is showing -548mV...
  16. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    RealAEL Sir,
    Yes , I have connected the ground wire at the bottom layer(it is shown in the screen shot of bottom layer of PCB), BLUE wire shows the ground connection.

    RealAEL Sir,...
  17. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    Sir,
    I agree your suggestion,now already PCB is designed, I have only option of changing the existing components. How can I add blocking capacitors (100pF) on either side of the meander...

    Sir,
    Herewith I attached screen shot of Board
  19. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    Sir,
    I have applied 3volts supply voltage, the difference of gate and source voltage (Vgs) is appearing +567 mV as simulated. The simulated Vgs( the difference of gate and source voltage)...
  20. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    RealAEL Sir,
    As you said, I followed it. I have re- attached transistor to board correctly( I have checked the continuity using the Digital multimeter of all 4 leads...
  21. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    Sir,
    I checked the properly the polarity of the multimeter, it was correct only. Polarity of the multimeter is not reversed. Now due to positive voltage of the gate, amplifier is...
  22. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    RealAEL Sir,
    As you told, I followed it. I took transistor off and checked the Biasing, now it is coming correctly Vgs = +567mV and Vds= 2.99 V, but Drain current is showing "1mA". Later...
  23. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    RealAEL Sir,
    I am herewith attaching my screen shot of LNA design generated layout, which has given to PCB design and got the PCB design. As I discussed in the earlier postings,...
  24. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    Sir,
    When I simulated USING ADS , Vgs was +568mV only. After the PCB design and component placing, it is showing the negative 500mV(-500mV). Which one I have to trust, whether simulation is...
  25. Closed: Re: Queries on Simualted and measured Biasing Values of LNA design in ADS

    Volker Sir,
    I didn't understand, what you asked.By setting proper bias voltages Vgs,Vds, and Ids, amplifier will amplify the signal otherwise it won't amplify. I have set the...
