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
Check out our device he

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


So you drop from 20 Gp (db) at 30 MHz to 8 Gp (db) at 100 MHz
Would not have been my choice.

BTW, is your equipment FCC type accepted for USA usage on the commercial FM
frequencies (as required)
