"Hello, I am an electrical engineering student. I am working on a design project related to high-frequency amplifier circuits or high-order active filter circuits in applications such as antennas and audio systems. Some project requirements include determining technical specifications, selecting a circuit schematic, calculating theoretical parameters, and simulating the design using software.

I am considering designing a high-frequency amplifier circuit for audio applications, but I currently have no clear direction on how to proceed with this project. Could you provide some suggestions regarding the project requirements?

I am not from an English-speaking country, so my English so such. I hope everyone can understand and be patient with me. Thanks u for help me"

 

Welcome to AAC!
Your English is fine.
Why do you want to use a "high-frequency" amplifier (which suggests one intended for frequencies higher than ~20kHz) for audio applications?

What is "high-frequency"?
How much output power?
If you search for "audio amplifier" you will find hundreds of different circuits.
Pick one that has the output power you want.

Below is one of my favorite (Marleyx) designs for a simple, medium-power audio amp with negative feedback from the output stage to the differential input stage, for both good DC bias stability and low-distortion output.

 

applications such as antennas and audio systems.

Normally antenna and audio are not the same type of amplifier.

 

You can simulate a low power AM transmitter.
When planning, it is smart to check the requirements in the country where you live.

When making a transmitter a BOM (bill of materials) can specify very practical parts in detail.
For example. You may want to use either a cell phone, an mp3 player, a laptop or microphone as an audio signal.
As an example you specify the cable with jack to be TRS 3.5mm 4 core using CTIA standard with right angle and wire size for soldering.
Because you specify and write down this information, later others can replicate what you made.
