noise figure :
This drawing shows an example of assembly and bias configuration. All the
transistors are internally self-biased. An external capacitor is recommended for
the positive and negative supply voltages.
For the RF pads the equivalent wire bonding inductance (diameter=25µm) have
to be according to the following recommendation.
(1) This value is the total length including the necessary loop from pad to
For a micro-strip configuration a hole in the substrate is necessary for chip
assembly.
