Dear all
I'm modulating a 1.1 GHZ frequency with the ADL5391 with an input analog signal of 10 to 20 MHz bandwidth. The result is a 1.1 GHz AM modulated carrier and it's sent through a rotating capacitor to a receiver.
In my application , I'm generating several carriers , all spaced of 100 MHz , like 1.1 - 1.2 - 1.3 - 1.4 ... GHz up to 1.8 GHz as I have 8 analog signals . Signal 1 will modulate carrier 1.1 GHz, signal 2 will modulate carrier 1.2 GHz and so forth.
All carriers are then mixed (passive ) and sent through the same spinning capacitor (100 pF , 2 plates).
Taking into account that all 8 carriers will come mixed together , what's the best way to demodulate each carrier and get back the analog signal ? Could the ADL5391 be used as an AM demodulator ? Any advice ?
Thanks to all
Max
