Greg,

We use a THA15/SD1726 (30MHz bi-polar 150w pep) producing 220w in our FM
PA in continuous duty service in the 87.5-108MHz broadcast band.

Yes, it needs plenty of drive and the heat sink require plenty of air
but at $30 USD a hit it's one economical and rugged amp.

Here it is: http://www.transmittersrus.com/shop/powerRF220.htm


That's odd, since the SD1450 specifications were for the commercial FM
broadcast industry (88 - 108 MHz),
and is rated at 150 watts for 18 watts drive. Price is virtually the
ame - maybe its higher for you in UK
Where did you get the SD1450 from!

Check out our device he

Give it a minute to load as it's a PDF page.
