how to make 2.4 RF transceiver using SDR

[tintin_99]

Hi, sorry if I have posted this in wrong section

I'm looking for an easy to get started transciver development board with ADC capability and 2.4 GHz mixer

My initial requirement is

- 1 channel ADC input, sampling as fast as possible

My question is , how difficult it is to make my own transceiver . I am not new to mixers , filter and analoge components and circuits in theory but I have no practical experience

if yes I would appreciate if you could give me some advice on how to start.The most important issue for me is price. the is the reason I decided to make my own transciver.

Thanks a lot!

Hi tintin,

Welcome to the NI Forums. The forums are generally used for support of National Instruments products and are frequented by NI Technicians, you may therefore struggle to find much discussion on building your own products.

However, there is an interesting article here in which a university student shares his design, code and board files for a home-made RF transceiver device.

I would also like to point you out to a new product of ours, the Vector Signal Transceiver. You can find out about this device here.

Thank you,

Hi Eden,

many thanks for your reply and the link. it was a great help.really appreciated

you know my plan is to use this RF transceiver with a microcontroller ( for decision making and baseband signal generation ). even I have a plan to implement FPGA in future to speed up the processing time and in the end I want to design and build somthing like USRP but completely specialized for my application . This is the reason I asked this question. Do you think is it a good idea to use my own   RF transceiver or it might be waste of time and it is better to use a commercial one and focus on the micro and FPGA part?  what is really important for me to be able to use NI FPGA and LabVIEW throughout this project.

Hi tintin,

I guess it would depend mainly on two factors - time and money. Consider your budget, it'll probably be cheaper to use your own custom build transceiver, but clearly more time costing. You should also consider resources available to you (especially with testing the device, troubleshooting issues etc.)

Basically, I can't tell you if one way will be better than another because it is all situational. However, if you can get a commercial one with built in FPGA then I don't see much need to custom build, as this will be able to do most of the specialisation you require.

I hope this was of some help, I wish you all the best with your application!

Many thanks,
