HELP, tellme a company to provide high frequecy power FET

I need to complete a 30W power amplifier module, but the frequency is 14-14.5GHz. Except the company of excelics, anyother company can provide the FET or transistor? I want to compare the price.
Thank you!

toshiba and fujitsu

I have gone to the two company's website, but I have not got what I want. Could you introduce another company?
THANK YOU!
