Open Loop Control Mode
With PAC ENABLE at a logic low, the voltage applied to VAPC is
buffered and applied directly to the bases of the RF devices. This
mode of operation provides backward compatibility with the
existing amplifier designs and allows for various test scenarios. As
with previous designs, an active clamp acts as a protection
mechanism limiting the maximum voltage that can be applied to
the base of the RF devices. This clamp voltage decreases with
increasing supply voltage.
The enable threshold on the VAPC input for open loop operation
exhibits a wide tolerance, which may vary from 200 mV to
800 mV. When enabled in Open Loop mode, the internal PAC
circuitry (V-I converter and integrator) is placed in standby.
