Watkins-Johnson’s SA1076 Power

Amplifier provides exceptional

linearity and low vector error for TDMA

digital modulation applications. Utilizing

WJ’s GaAs amplifiers driving bipolar

transistors in the class AB output stage,

the SA1076 achieves a high third-order

intercept point combined with superior

efficiency when compared to an equiva-

lent power class A amplifier. Special non-

linear design techniques are utilized to

minimize unwanted adjacent channel

power. To aid top level system diagnos-

tics and reliability, the unit includes

alarms to identify if an active part fails

or if a poor load is presented to the RF

output. In the event that a fault is detect-

ed or to simply save DC power, a digital-

ly controlled shutdown is provided. An

integral logarithmic power detector mea-

sures the output power of the amplifier

over a 16 dB dynamic range.
