I am trying to generate a 27MHz carrier signal to transmit it through a loop antenna, I referred many circuits couldn't able to find the one I need. can anyone guide me on generating it using a few simple transistors or using an oscillator chip with a 3v cell battery? The thing is my design is...
Hello,
I would like your suggestion on my first design Differential signal modulator [simulation attached].
Before jumping into design let me highlight my objective. I am differentiating a control signal of 1MHz and then modulating it with carrier frequency 15MHz(not limited to this specific...
Hi,
I am trying to build a lock-in amplifier circuit using AD630. But the signal which I wanted to detect is in the megahertz range and AD630 is not functioning in this region. So, is there any device which can do lock-in like AD630 but in a higher frequency region?
Thank You.
hey guys, I hope all is well. I have a question about the following two schematics. One is a high power IR transmitter and the other is a long range ir transmitter. When I look at them both I feel like they're doing the same thing just in a different way. Would I be correct to assume that they...
