I have not yet put my hands on one of them but it is on the list. I 
wanted to suggest a different video speed opamp from Motorola but I 
found this instead while looking for the datasheet. I like the very low 
noise at HF-VHF. This could make a very nice IF amplifier and even a 
front end. But I don't understand why the noise is much higher on the 
(-) input.
