Hallo John

I was triing to find a solution using Apex PA85 amplifier. But an PA85 is litmitted to 200 mA output current ( By 500 kHz, I need ca. 1 A). And if I take one or more PA85 in parallel mode, so hole system will slow down. I can't reach the speed any more. But if I look to APEX selection guide, so is the PA85 the only amplifier reaching speed and voltage I like.
So actualy I an looking for an other possibility, like to build my one amplifier using MOSFET or so. But I haven't found a solutiuon now.
