Abstract
An amplification unit contains two or more sets containing a plurality of amplification circuits, and amplifies power of an RF (Radio Frequency) signal. A combining unit contains two or more combiners corresponding to the two or more sets, combines RF signals output by the amplification circuits, and outputs a resultant RF signal. The amplification unit and the combining unit have two or more connectors which are arranged transversely. The amplification unit and the combining unit are attachable/detachable.
Claims6
A power amplification apparatus provided in a television signal transmission system,
- the power amplification apparatus is accommodated in a rack, and
- the power amplification apparatus comprises:
- an amplification unit, containing two or more sets containing a plurality of amplification circuits, that amplifies power of a radio frequency (RF) signal;
- and
- a combining unit, containing two or more combiners corresponding to the two or more sets, that combines RF signals output by the amplification circuits, and outputs a resultant RF signal,
- wherein;
