Typical Assembly and Bias Configuration
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) has to be according
to the following recommendation.
Port
IN (2)
OUT (8)
Equivalent inductance
(nH)
L_in = 0.27
L_out = 0.27
Wire length (mm)
(1)
0.34
0.34
(1) This value is the total length including the necessary loop from pad to pad.
For a microstrip configuration a hole in the substrate is necessary for chip assembly.
