3.1 Bias Mode Control Pins

The amplifier bias modes can be controlled by populating jumpers, J12 and J13, or by populating the SMAs, J4 and J5, to directly apply a signal. If using the jumpers, shorting terminals 1 and 2 pulls the pin high, while shorting terminals 2 and 3 pulls the pin low. J4 and J12 control the first bit selection, A0. J5 and J13 control the second bit selection, A1.
