Find BPSK Modulator Chip for Project | BPSK Code

[bearbear]

i'm doing BPSK modulator for my project. can anyone please tell me where can i find a PSK modulator circuit? or a BPSK mdulator IC chip?wat is the code for the chip.

Welcome to the PF. What is your background? What class is this a project for? What learning materials are you using to understand modulation in general, and PSK in particular? Here is a basic reference about PSK:

http://en.wikipedia.org/wiki/BPSK

One fundamental circuit element that can be used for modulation is the Gilbert cell. Check out the App Notes on Mixers at this MiniCircuits.com page:

The old LM1496 is the basic Gilbert cell mixer chip, but you will need some circuit skills to use it. The simplest thing might just be to buy a mixer module from MiniCircuits...

help

thanks for your reply. but i can't find the circuit. can u please send me the complete circuit instead?

Nope. You need to do the legwork -- that's what a project is for. To help you learn about the subject, and to learn how to find information and use it. I'll give you a little push in the right direction, though... Go to www.national.com (the National Instruments website) and do a search on LM1496. That will give you several application notes, etc., on how the part is used for modulation. In case you have trouble getting there and doing the search, here's the hit list:
