Hi
PA is always matched to the Optimum Load which we can get from the load pull simulation of the device if you have model available for the simulator.
dont worry about the mismatch between antenna and the PA output. Use isolator between antenna and PA output.

Hi
what kind of signal will be sent to reciever? some control or configuration signal or something else?
why four receiver? are they installed at different places?
decision of realization technology will depend upon the range u want to cover and power of the transmitter and the data rate.

Hi
The GCS and PBIN parameters are affecting more in my case. but still i could not see more than 4dB improvement in IMD. is this the real improvement from the MAX2009?
this is the im[provement when i am giving simple CW 2 tones.
any suggesstions...
After some when the amplifier is running...
thats is good that you are simulating with Vias holes. it will reflect you all the problems before you make the PCB. the most important prarameters for the via is conductivity, height, diameter. you have not taken the realistic conductivity.
the Vias holes are adding an additional inductance to...
Hi thanks
i will try this on moday. i were getting good IMD when i checked the PA without predistortion but as soon as i connected predistorter it gets worst than before. So i thought it may be due to unoptimized predistorter parameters.
I am using the LDMOS big base station amplifier. I am trying with open loop. right now i am optimizing the MAX2009 parameter with 2tone CW signals from sig Gen.
Hi
Anyone can guide how to get optimum performance using max2009?? I am not getting any improvement in IM3. whtever i change is causing the IM3 worst. Please help.
