connecting sequenser to evaluation board

[yefj]

Hello ,I have built a sequencer for the following device with three outoputs Vg1=-2 Vg2=5 Vdd=+12
When I look at the layout I marked the GND pins with red.
which pins should be connected to Vg1?
Thanks.

The central component labelled A1 is likely the active device (such as a GaN or LDMOS transistor). This device will have multiple connections: Gate(s), Drain(s), and Source(s). Typically, Vg1 (-2V) is used to bias the gate of the first stage (input side). Vg2 (+5V) is usually used for the second stage or to control gain in some devices. The Drain (Vdd = +12V) will be connected to power-supply nodes. The red-marked GND pins indicate the source or ground connections. The Vg1 (-2V) pins should be connected to the gate terminals. The left side of A1, where the signal enters, likely contains the gate pins. The small passive components (capacitors, resistors, inductors) near this region likely form a gate bias network. The pin(s) closest to input matching networks should be connected to Vg1 (-2V). In the annotated areas (blue text), there are possible biasing components. If you have the datasheet of the component, please consult that before making the final connections.
