Hi

 

looking for high power high frequency amplifier that will be connected to ultrasound ceramic

 

I am not HW person so help me to ask the right question

 

basically

 

input output

- up to 20 Mhz pure sinuous

- controlled or around 20 gain

 

input

- up to 3 V p-p (drived from AD9580 dds board)

- 50 ohm

 

output

remark: as ceramic may be broken and change its resistance

we need to take some caution the output leg

- up to 60 V p-p

- changeable output resistance that will not harm amplifier 0-inf

- changeable output resistance that amplifier can handle 5-200 hom

- changeable output phase that amplifier can handle -60 to 60

 

probably some cooling device

 

where to start?

what else to ask?

 

thanks

 

also: would like to connect only vrms measure to the output , any suggestion?
