rd100 strip paSergey (EX9T) came up with the new design. With 3 W input and 15.2 VDC, this thing gives nearly 90 W output on the band. Not bad. This will be a good PA for the UT5JCW transverter providing about 10 W output. Note that the PA has LPF there so the harmonic output is in line with regulations.

This is how it looks like assembled on the test-bed:

This is how it looks like assembled and ready to be installed into UN2G's transverter:
