The performance of any phased array is critically dependent upon proper
[phasing] and [amplitude] of
the power delivered to each element in the array. If we consider only the
transmitting case, this
is almost impossible to accomplish with what your are proposing.
The phase from the central feed point to the input of each element amplifier
can readily be
controlled, but how do you plan to control the phase shift through each
amplifier at the element?
No two power amps exhibit the same phase shift when matched to the load
impedance ... PERIOD ...
there are literally an infinite number of L/C combinations which will match the
amp to the load, but
each one exhibits a different phase shift. Amplitude control is possible (at
great expense of
complicated circuitry), but each element of a phased array must have precise
[phase ]AND [amplitude]
of power applied to it.
And how do you propose to handle the reverse situation (on receive) ... the
amps you are
contemplating ARE NOT BI-DIRECTIONAL !!!
I don't think what you are contemplating is realistic from an engineering point
of view, let alone
