| 摘要 |
The disclosed multi-stage amplifier (200) comprises several amplifier stages (201-203) which, together with an output network, form different branches. A first branch comprises a first and a second amplifier (201, 202) having their outputs connected to each other via a quarter-wave transmission line. The first branch is connected to a load via a first offset-transmission-line (0.1). A second branch comprises a third amplifier stage (203) and a second offset-transmission line (0.22) which are also connected to the load.
