    IP3 is low for a power amplifier

    hello everyone, i designed an LNA but OIP3 values are nearly -6 and -9 dB.. i think they are very small, what should i do to increase them.. with "they" , i mean 2*f1-f2 and 2*f2-f1 shouldn't they be equal, by the way ??? king regards

    What is the relation of P1dB and IP3?

    hello everyone, i designed an LNA but OIP3 values are nearly -6 and -9 dB.. i think they are very small, what should i do to increase them.. with "they" , i mean 2*f1-f2 and 2*f2-f1 shouldn't they be equal, by the way ??? king regards

    BFP740 AWR model nonlinear analysis problem??

    thank you for post. should they be equal? in my design, 2,-1 and -1,2 are not equal, what is the reason for this? gain can be said to be nearly flat. Cem

    BFP740 AWR model nonlinear analysis problem??

    hello again manju, first, thank you very much for your help and time. your advices are very helpful for me, i'm really grateful. i have one last question; i should measure the third-order intercept by using two -20 dBm input signals at 2.44 and 2.46 GHz. i start frequency range in "project...

    BFP740 AWR model nonlinear analysis problem??

    hello, i am using two tones and swept already but couldn't find the problem again, i cannot make OIP3 analysis again :( i am attaching the .emp file , if you could have a chance to look at, i will be grateful. i also write some explanations in "design notes". thank you for your help, looking...

    2.4 lna design narrow bandwidth

    i already used two tone signal, which are at 2.44 and 2.46 GHz and -20 dB but it gives the same error again :(

    BFP740 AWR model nonlinear analysis problem??

    hello everyone.. we are designing a LNA using Infineon bfp740 and simulated it on AWR Microwave Office. in Infineon website, they gives AWR model of the transistor, but we can not have nonlinear analysis, for example; OIP3. it gives the error message "the interception point measurement must...
