I am trying to find a coaxial surge protectors that is maching items below. I found Erico surge protectors (https://m.erico.com/category.html?category=R1408&country=us&language=en ) but it's datasheet doesn't have all below specs. Which model is that I need?

-Providing surge protectors with operating temperature from minus 40 deg C to plus 100 deg C.
-Protectors shall be bi-directional with no signal loss.
-Provide in-line protectors.
-Moisture Resistance: MIL-STD-202.
-Maximum Power at 50 Ohms: 500 watts.
-Breakdown Voltage at 100 Volts per Second: 200-300 Volts.
-Residual Voltage at 1 kVolt (U.S.): Less than 600 volts.
-Power Handling: 10kA at 10 shocks, and 20kA at 1 shock.
-Return Loss for N Connectors at 1 GHz: Less than minus 25 dB.
-Insertion Loss for N Connectors at 1 GHz: Less than 0.03 dB.
-Housing: Copper alloy with CuZnSn finish.
-Insulation: Teflon per ASTM D-170.
-Contact Shocks: Gold plated copper alloy or beryllium copper.

I have no idea.

But I would suggest that the gold spec be 50 millionths gold over nickel over whatever. The reason is that gold is porous and I believe even at 50 millionths copper corrosion will bleed thru the gold. The under layer of nickel is non-porous.

My answer would be the suggested products do not meet your required specifications. Temperature fails, inserting loss fails, and others may also fail.

But the suggested products look good.

The surge protector below looks close to what you want with the type-N connectors that were specified. The return loss, maximum RF power, and surge current capability meet or exceed your specs. The insertion loss is a maximum of 0.1 dB over the 698 MHz to 2.7 GHz range so it is very low. The IL spec of <0.03dB you had at 1GHz may have been typical, and in any case an insertion loss that low is very difficult to even measure reproducibly.
