Watkins-Johnson’s SA1083 Power Amplifier provides exceptional linearity for CDMA digital modulation applications. Utilizing WJ’s GaAs amplifiers driving bipolar transistors in the class AB output stage, the SA1083 achieves a high third-order intercept point combined with superior efficiency when compared to an equivalent power class A amplifier. Special non-linear design techniques are utilized to minimize unwanted adjacent channel power. To aid top level system diagnostics and reliability, the unit includes alarms to identify if an active part fails or if a poor load is presented to the RF output.
