[Samudra Haque]

Hi does the spec specify the output power as EIRP or not?

If EIRP the antenna gain needs to be part of the equation and
therefore you need to reduce your transmission power to avoid desense
at the receiver on orbit. If the spec does not specify then there
should be a receiver senstivity figure already published which would
be useful in a link budget equation.
