I am trying to design an RF transmitter using LMX2531 for phase locked loop.Apropriate component for my application is LMX2531LQ1650E as my transmit freq is inside its range of operation. According the link budget analysis that i have made transmit EIRP is -5,327dB which means almost 300mWatt.
I want someone to help me finish my design after PLL up to antenna connector.
For my point of view iam thinking of a midium power amplifier and High Voltage Transistor and afterwards a band pass filter with a NPN transistor.
Should i consider the chain after PLL according this 300mWatt EIRP transmission. Or this is antenna mater and must think something else?
Also does someone know any kind of low power consumption chipset that would be able fullfill my requirements?
The LMX2531 is very low power device and an excellent choice. The National Clock Design Tool can help with the design of that device. To get this just go to www.ti.com and type in "National Clock Design Tool" in the search box.
As for finishing the design from the PLL to the antenna, I am not very familiar with these, but we have another RF group that deals with these. If you go to www.ti.com and click on the "Applications" tab, there are many links to system diagrams that can recommend parts that might be of use to you.
Thank you very much for this info. I have already downloaded this National Clock Design Tool and helped verify the frequency at OSCin of LMX2531.
P.s Do you know why National Clock Design Tool cant run at Windows 7. At XP is working fine.
Windows 7 is causing many problems with our internal software because it was developed a long time ago. The long term plan is to actually replace this tool with another one that we are working on now.
