Abstract
An amplifier module that implements two or more amplifying units connected in series is disclosed. The amplifier module includes a package, input and output terminals, two or more amplifying units including the first unit and the final unit, an output bias terminal for supplying an output bias to one of amplifying units except for the final unit, and an input bias terminal for supplying an input bias to another one of the amplifying units except for the first unit. A feature of the amplifier module is that the output bias terminal and the input bias terminal are disposed in axial symmetry with respect to a reference axis connecting the input terminal with the output terminal in one side of the package.
Claims13
An amplifier module, comprising:
- a package having one end and another end opposite to the one end;
- an input terminal arranged in the one end of the package;
- an output terminal arranged in the another end of the package, the output terminal and the input terminal being arranged on a reference axis that connects the output terminal with the input terminal;
- two or more amplifying units including a first unit and a final unit, the amplifying units each arranged on the reference axis and connected in series between the input terminal and the output terminal, the amplifying units each having an input and an output;
- an output bias terminal connected with the output of one of the amplifying units except for the final unit, the output bias terminal supplying an output bias to the one of the amplifying units;
- and
- an input bias terminal connected with the input of another one of the amplifying units except for the first unit, the input bias terminal providing an input bias to the another one of the amplifying units,
- wherein the output bias terminal and the input bias terminal are arranged in axial symmetry with respect to the reference axis in one of the one end and the another end of the package.
