I wold like to know whether
Feedforward linearisation can be implemented without a variable gain
and phaseshift mechanism.(completely in RF, without anydigital processing
or microcontrollers).

As a general statement, whether or
not you need adaptive circuitry for feedforward linearization depends
on how stable (in a general sense, not "will it oscillate?") your design
is. If parameters change with time, adaptivity is critical - because
feedforward depends on cancellation of distortion products, delay and
amplitude control is critical.
Good Luck!
