Hi,
I need help in doing amplitude modulation with a quadrature modulator component.
I want to create a modulated signal with a 10kHz signal + 2.4GHz carrier frequency (I've found a chip to generate the 2.4GHz). I was looking on digikey for a modulator and most of the results I get give me quadrature modulators (e.g. https://www.electro-tech-online.com/custompdfs/2010/04/AD8346.pdf).
I don't have extensive knowledge in signal stuff and this is what I'm seeing so far for the quadrature modulator: Is the I and Q inputs for the 2 signals I want to modulate? If I just want AM, what would I put into the LO input of the component?
I'm sorry, I've read the spec sheet and googled how quadrature works, but it's going over my head. If someone can give me a simple explanation, I would really appreciate it. Thanks in advanced!
