Re: Recommend transistors for PA at UHF?

Are you building an amplifier from scratch? If so, I recommend using "brick" RF modules. They are so simple...just mount them on a heatsink, wire up a couple of voltages, feed them with the proper input RF level (usually in the 1-200 mW range) and take the output from the module and run it through a low pass filter to the antenna. See http://www.rfparts.com/module.html for available modules and frequency ranges. They have many modules for the range you seek. Most modules listed have data sheets at that site as well.

Can anyone recommend power transistors for 25W PA, for 450MHz and 900MHz.

Thanks
