AD8347 mixer loading

Hello

I have some questions from my one of my customers in regard to the device:

1. In non-AGC mode, does he need to place a protection device (PIN diode/limiter) on the input to the mixed to prevent damage to the output of the mixe?
2. If he'll use a filter on MXO pins (200 Ohm load, Chebyshev ) can the device be damaged when the current is limited to 1.5mA or there will be only clipping ?
3. Is there any data on radiated or conducted susceptibility of the device especially per MIL-461 standard?

BR,

Alon
