Watkins-Johnson’s SA1056 Power
Amplifier provides exceptional
linearity for CDMA digital modulation
applications. Utilizing WJ’s GaAs
amplifiers driving bipolar transistors
in the class A output stage, the SA1056
achieves a very high output third-order
intercept point combined with superior
efficiency.
