high frequency amplifier design

[f.gh]

Hi

I want to design an amplifier which works properly in 100kHz frequency, If anyone introduce me some simple and practical structure, I'll be so grateful.

"Amplifer" is a very generic and general term. What type of voltage and/or power gain do you need at 100kHz?

You are right, I need a power amplifier which can give me about 700watt power and about 10A current.

Most designs will use linear amp topologies (class A, AB, B). With such topologies the choice comes down to a tradeoff of distortion vs power efficiency. More modern designs may use class D/G/H but those are much more complicated to control.

Such high power designs are not common. You may want a bridge configuration to minimize the high voltages required (700W @ 10A requires a pk-pk output voltage of 196V for a sine-wave).

What is the purpose of this amplifier?

The purpose of this amplifier is to create an electrical field by using a coil in it's output. could you please introduce me a structure?

The purpose of this amplifier is to create an electromagnetic field (instead of electrical field)
