Hello, I have this datasheet. It is in the form of a 150k .zip file that becomes 5 .tif files. They are not the best quality but they will work. I downloaded it off the net but I dont remember where. I think it came from rohm, but thats a guess. You can try getting it off the net, or email me privatly and I will send it to you, or anyone who wants it. If you find a better way to control the transmit frequency let me know. My circuit works well but drifts quite a bit with temprature variation. Thanks, Andrew - kn6za >- Microhard Feng wrote: > I need BA1404's datasheet, any advice welcome. > __________________________________________________ Do You Yahoo!?
