    predistortion and S-parameter (S11) unmatch problem

    This is my schematic. Everyone knows the function of the predistorter which is just like this figure. Now , my question is if the s11 of amp is not very (ex -3dBm). Is the result still good as this figure?

    predistortion and S-parameter (S11) unmatch problem

    thanks for help. Asssume, my predistorter can improve the imd of amp about 20dBm Does the improvement of the predistorter become not very well, if s11 of Amp is not lower than -10dB ??

    predistortion and S-parameter (S11) unmatch problem

    hello , As the title, I make a predistorter by using diode and combine with a AMP to improve the IMD of the AMP. However the s11 of the AMP is not very well. Is the IMD of the AMP still improve well when S11 of the AMP is not very well?

    power depend pin diode sensitive to RF field

    Re: power depend pin diode Yes, the situation that you talk is exactly what i want. how a pin diode can sensitive to rf power ? is that possble? I need a pin diode that R is easier changed by rf power. what kind pin diode or component can achieve my need?

    about pin diode linearity

    biff44 thx a lot you give a good idea I have some question about the antiparallel shottky diodes. As we know , this circuit will be some inertion loss maybe S21 = -3dB 1.does this circuit 's insertion loss will be the same magnitude at each frequency in 500MHz~3GHz ?? 2.does this circuit 's...

    about pin diode linearity

    I am really sorry , I am not good in english. I need a component. This component is wideband. For example, its s21 is flat in 500mhz ~ 3000mhz. and It's nonlinearity(intercept point) is same in 500mhz~3000mhz too [/img]

    about pin diode linearity

    thx karesz sorry about the sentence rewrite: I need a diode which have "same" non linearity characterist at each frequency (ex. insertion loss....)

    about pin diode linearity

    thanks for help biff44 I need some nonlinearity component which can generate nonlinearty characterist at each frequency (I mean broadband). That is why I choice pin diode but I didn't notice, it is high linearity. So what kind nonlinearity component can achieve my condition (broadband and...

    about pin diode linearity

    hello everyone I use some pin diode to do my experiment. now I have some problem. The linearity of pin diode always is good. but now I need a very poor linearity pin diode to do my experiment . so how can i make a poor linearity pin diode by using...
