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 equiva-

lent 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.

In the event that a fault is detected or to simply

save DC power, a digitally controlled shutdown

is provided. The amplifier is protected from

thermal overload by an internal temperature

sensor which triggers a digital alarm and shuts

down the power stages if the baseplate tempera-

ture rises above 95°C. An integral logarithmic

power detector measures the output power of

the amplifier over a 16 dB dynamic range.
