I need to duplicate a fast (~2GHz) analog signal to 2 channels.
To avoid signal integrity issue I won't to avoid "star-topology" and use an analog 1:2 fanout buffer instead.
1. What do you think about the solution ?
2. Please advice an appropriate IC.
What's unclear, the term voltage follower? You'll find plenty of buffer applications e.g. in OP data sheet.
The initial post is however missing many details:
- signal voltage range
- DC or AC coupled?
- expected/required impedance matching
- acceptable gain/phase/waveform error
