Hi,
finally the 500w 2,4ghz ready fo DVB-S2 tests. Designed by myself with Ampleon USA supports.
Produced by Fausto Coletti.
See the pictures.
Next Sunday DVB-S2 portstdown streaming tests with 250w new PA 105cm uplink dish.

Super !
Planning to cook pigeons ?
Hi,
not at all I prefer seafood. It rained a lot in Italy during this month but not to have
flying seafood .
In reality the dual ldmos is 500w CW, I'll use it at around 200w DVB-S2 to get better shoulders.
I've also modified the pcb taking out the output Duroid section and placed RG142 cannot stand more than 300w at 2,4GHZ.
I've forgot to tell the Fausto Coletti call sign is IK4NMF, he manufactured the 500w PA for me.

Hi,
first 500w Ampleon Pa tests, first changed PA to 105cm cable to 1/2inches Cellflex to stand up to 700w at 2,4Ghz as in attacched 105cm-ofset.jpg.
First dattv tx trial at 1Msymbol immediately stopped due to over power.
Second tests 2Msymbol see pictures 2Msymb.jpg.
Last but not least new upstation see Upstation.jpg.
Power around 130w shoulders 50db.
Bye!
Project doc completed.

Hello,
I'm also interested in this 500 Watt PA. Can I buy an item from Fausto Colletti or can you support me in my own construction and development. Where can I get the PCB for the LDMOS Power transistor?
