Best Wishes from my heart to you...
Good Bye,

Ahmad,

I said I could.

Unfortunately I can't afford to give you a week of my time for nothing.

I agree with you in that in fact, You're absolutely right... but...
But I may really be unable to pay mony for it, because i have no credit card and i wont be able to have one at this time, I'm ashamed ...

You cannot change the BW significantly.

I could design a discrete solution, but it would take time and money.
But since this is for your thesis perhaps you should design it to earn the degree.

433 modules are out there, thousands of them:

TDA7000 is a very special design with 75KHz IF frequency, you cannot just change
this to 455KHz or any other IF frequency.

There are a number of ready-made modules sold by all major electronics vendors.
Usually working at 433MHz. This is your best way.

Thank you for your immidiate reply :)

For ...

You ideas are bad, it cannot be done that way. You did not really read the datasheet
carefully.

Use another IC.

Okay, First, Thank you Mr. Administrator, and i want to tell you that i did read the data sheet carefully as well as the application note AN193 many times before i post this post, and ...

Guys!
Please help me in my problem, I'm really in harry and trouble due to my graduaiton project!!!
I need to build high bit rate digital data link using TDA7000 in its Rx end ,

I heared that TDA7000 can be modified somehow to allow wide band transmission, but i don't know how,

I thought that ...
