atkins-Johnson’s SA1106 Power Amplifier
provides exceptional linearity for TDMA
digital modulation applications. Utilizing WJ’s
GaAs amplifiers driving bipolar transistors in the
class AB output stage, the SA1106 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 sen-
sor 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.
