Signal-Gain
Notes:
1. Input referred noise = RMS output noise/low frequency gain. Input referred, 55MHz.
2. Input is a 200MHz square wave, t
r < 300ps, 1.8VPP.
3. With input signal V
ID > 5mVPP.
4. Input is a 200MHz square wave, t
r < 300ps, 50 load.
5. V
ID > 5mVPP.
6. Output levels are based on 50
impedance. If the load impedance is different, the output level will be changed.
7. See output structure.
