A fast DIP comparator such as an LT1016 should work but it won't perform well without an effective ground plane.
If a CMOS gate is used then a low Q LC impedance step up network or equivalent will be needed to increase the signal swing at the gate input. Add a couple of schottky diode clamps for overvoltage clamping (internal CMOS gate clamp devices usually degrade performance if they conduct).
