Maximum allowed reverse output power on RFOUT of HMC816LP4E

I have used HMC81LP4E as Low Noise Amplifier, with 20 dB gain and 0.6 dB Noise Figure, at 3.3V supply with 437 MHz Half Duplex System. With cascade of two, I get a LNA system of 40 dB gain and 0.65 dB Noise figure. I want to know the maximum reverse output power on RFOUT port, so that 2nd IC doesn't get damaged. Also, can the IC survive the maximum allowed limits mentioned in the datasheet if its OFF? I know the IC is now not recommended for new designs, but I need to know its detailed specifications, much more than what datasheet has provided.
