rfsystem ku band transmitter receiver SSPA

What do you think about this system?

TX power output:43dBm(SSPA output power)
Antenna gain 15dB ( antenna is on airborne and directional)

RX antenna gain 34dB ( antenna is directional and tracking reflector antenna 1.2dia

max range 200km
bandwith 200MHz(spread spectrum )
Data rate 10.71 and 45 Mbps

frequency 14GHz

So can i find a receiver in ku band with a sensitivity that can achieve this transmission
suggestions about receiver are welcome
Also about transmitters and SSPA taht can be used for this link....

The free space path loss at 14GHz for 200km is 162 dB (without margin for humidity, fading, etc)
From link budget calculation that you have, results approximately -70dBm signal level at the input of the receiver, that should be ok for the data rate that you are looking to transmit.

Mitsubishi makes some good receivers for Ku band:

but if i add 30dB fade margin will may data link achieve transmission from 200km in bad weather conditions.

Can i establish a receiver+antenna system for sensing -100dB signal
or is -100dB signal is meaningless for data transmission

and what are the signal ranges that are sensed in systems like these
i mean -80,-90dBm

Thank you very much for your interest and help

-80dBm including fade margin is a good input level for the data rate that you are looking for.
30dB for fade margin I think is too much. Usually for this case is approximately 20dB.
