RD series
Rob M0DTS published an easy to construct design using the RD series of FETs in CQ-TV 247 and 249 - a good way to get a clean 5 watts on 146 MHz. (The full article is available in high resolution in the magazine)
Or have a look at M0DTS web page. http://www.m0dts.co.uk/index.php?tag=146MHz
Mitsubishi power modules
The Mitsubshi RA60H1317M 60 watt brick can be driven via the YU1LM filter and a 10 dB attenuator from the Portsdown transmitter to provide approximately 7 watts output.
