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.
Ready built amplifiers using this module are available from DG0VE or Bert Modermann PE1RKI http://www.pe1rki.com/
Minikits are a good suppler of kits = http://www.minikits.com.au/ specifically http://www.minikits.com.au/electronic-kits/rf-amplifiers/rf-high-power
For those who want to roll their own, the components are available from the following
- Sam Jewell G4DDK, 8W amplifier kits uses the same PCB as the 60 watt version.

- Anglia Live, suppliers of Mitsubishi power modules
- 60W power amplifier pcb (available from G4DDK above)
