ABSTRACT:
An RF radiating system possesses high efficiency and reliability, including built in rain margin capability, in a structure that associates a plurality of solid state RF amplifiers with an antenna in an antenna array. In a specific aspect the system comprises a plurality of sources of RF carrier signals of at least two different frequencies; and radiating means for radiating an RF signal of a given frequency in multiple power levels in a first directionally steerable beam and for alternately or simultaneously radiating at least one additional RF signal of a different frequency in a directionally steerable beam separate from said first beam; said last named means including a plurality of discrete solid state amplifier means for coupling and amplifying signals from said source to said radiating means.
