I am working in 100GHz for RF design of power amplifier and want to know the ideal value of 1dB compression point for it. and how to relate it with frequency?

Does ANYTHING operate at the ridiculously high frequency of 100GHz??
The P-1 dB is not a component parameter but system parameter.
Depends on the application you intend to use your amplifier.
\Due to small chip size and transistor features, at ~100 GHz such "power" amplifiers typically have P-1 dB point < +10 dBm. Special designs can have up to +20 dBm but it requires to use power splitters/combiners on the chip, and increases complexity and also potential instability.
At 100 GHz, if used for communication, systems can utilize antennas with a high gain, so power amplifiers do not need to generate high power level. In systems like radar, high power capability is welcome but costly to generate.

To Audioguru: Yes, there are many interesting systems that operate even higher, in THz range. Some also commercially available.
