High voltage, high frequency amplifier

Hello everyone,

I am completely new to the forum, in fact I was motivated to join after reading some of Webdog's old posts (hope he is still member) regarding ENI high voltage broadband RF amplifiers. Is there a possibility to obtain some detailed schematic of one of those amplifiers ?

I got some service manuals from E&I (they provide documentation for old ENI amps) but there is no detailed schematics, only some functional and block diagrams.

Can anyone help with this problem ? Webdog, if you are reading this, I tried to send you a private message but I can't since I had no posts (until now, I guess ).

It is important that amplifier covers range from 100 kHz to 6 MHz with voltage swing of max. +/- 150V and can provide output current to 250 mA. According to specs and some practical usages (in FT-ICR mass spectrometry which is my area) ENI amplifiers are highly regarded and widely used.

Can anyone provide schematics for one of these ?

Thank you all in advance,

Josip Miller

Hi,
You can i.e.. search for Piezo Driver circuits_their have often same specifications...
This are Webdogs all scripts_if helps for you:

Thank you for the reply. I already searched some piezo driving designs, I didn't find anything yet but I'll keep searching.

I'll appreciate if anyone has these schematics, they are really preferable. Other manufacturers are, naturally very reluctant to give away schematics to people who are not their customers.

Thank you,

Josip
