This drawing shows an example of assembly and bias configuration. All the
transistors are internally self biased. The positive and negative voltages can be
respectively connected together (see drawing) according to the recommended
values given in the electrical characteristics table.
For the RF pads the equivalent wire bonding inductance (diameter=25µm) has to
be according to the following recommendation.

For a micro-strip configuration a hole in the substrate is recommended for chip
assembly.
