Claim:
An out-phasing-array transmitter, comprising: 2 N switching power amplifiers to receive a signal, S(t), the signal being a summation of 2 N constant amplitude signals, S 1 (t), S 2 (t), . . . , S 2 N (t), for integer N, where the constant amplitude signals are defined by the following equations: S 1 ⁡ ( t ) = 1 2 N ⁢ r max ⁢ exp ⁡ ( j ⁡ ( ω 0 ⁢ t + ϕ 1 ⁡ ( t ) + ϕ 2 ⁡ ( t ) + … + ϕ N ⁡ ( t ) ) ) S 2 ⁡ ( t ) = 1 2 N ⁢ r max ⁢ exp ⁡ ( j ⁡ ( ω 0 ⁢ t + ϕ 1 ⁡ ( t ) + ϕ 2 ⁡ ( t ) + … - ϕ N ⁡ ( t ) ) ) ⋯ ⋯ S 2 N ⁡ ( t ) = 1 2 N ⁢ r max ⁢ exp ⁡ ( j ⁡ ( ω 0 ⁢ t - ϕ 1 ⁡ ( t ) - ϕ 2 ⁡ ( t ) - … - ϕ N ⁡ ( t ) ) ) } , ⁢ where ⁢ ⁢ r max ⁢ ⁢ is ⁢ ⁢ a ⁢ ⁢ peak value of an envelope signal, jω 0 t is a carrier frequency, and φ 1 (t), φ 2 (t), . . . , φ N (t) are out-phasing angles; and a table comprising values in degrees to be plugged into the out-phasing angles of the equations for a given input power; wherein a dynamic range greater than 35 dBm is achieved.
