Abstract
A power amplification device includes a first power amplification unit having the positions of connectors thereof reversed, a second power amplification unit not having the positions of connectors thereof reversed, and a heat sink having a first flank thereof abutted on the heat radiation surface of the first power amplification unit, and having a second flank abutted on the heat radiation surface of the second power amplification unit. A transmitter using the power amplification device includes a plurality of power amplification devices, a distributor directly coupled to the input connectors of the power amplification devices, and a synthesizer directly coupled to the output connectors of the power amplification devices.
Claims5
A power amplification device comprising:
- a first power amplification unit including a first power amplifier whose heat radiation surface, input terminal, and output terminal have a certain positional relationship, a first input connector disposed by the side of the first output terminal of the first power amplifier, the first output connector disposed by the side of the first input terminal of the first power amplifier, a first output lead connecting the first output terminal and first output connector, and a first input lead connecting the first input terminal and first input connector;
- a second power amplification unit including a second power amplifier whose heat radiation surface, input terminal, and output terminal have the same positional relationship as those of the first power amplifier do, a second output connector disposed by the side of the second output terminal of the second power amplifier, a second input connector disposed by the side of the second input terminal of the second power amplifier, a second output lead connecting the second output terminal and second output connector, and a second input lead connecting the second input terminal and second input connector;
- and
- a heat sink having a first flank thereof abutted on the heat radiation surface of the first power amplification unit, and having a second flank thereof abutted on the heat radiation surface of the second power amplification unit.
A transmitter comprising:
