Hi,
I am a beginner in RF analog circuitry
i have an optical fiber sensing application where the return optical signal is demodulated via optical demodulator and pushed out via RF output from a balanced hybrid reciever as discussed in
Product Datasheets 2/3/2007 (optoplex.com)
Now my issue, i wish to use a ADC for signal digital conversion
The RF voltage output in fact swings between +3v to -3v for high impedance loads and +1.8v to -1.8v for 50 ohm , what does this mean ?
how to handle this output voltage safely and carry it to an ADC ?
kindly suggest me an single ended to differential driver opamp that can be interfaced to the ADC directly
provided which can handle this input voltage up to a frequency of 100MHz input
I dont have ADC in my mind now, kindly suggest a ADC also for these high swing inputs
