5. Microwave-specific structures
5.1 Distributed amplifier
The structure (figure

) was designed to avoid the cut-off frequencies introduced by the transistor's input and output capacitances. Initially, this technique was applied to electronic tubes because of their high input and output impedances. Indeed, if the real parts of the input admittances Y
e
and output admittances Y
s
are negligible, we can write:
