摘要： A method and apparatus improve the performance of a carrier amplifier in a Doherty amplifier. The Doherty amplifier includes a power divider, a carrier amplifier, at least one peaking amplifier, offset lines, and a Doherty circuit. The power divider provides a power signal to each of the carrier amplifier and the at least one peaking amplifier. The carrier amplifier amplifies power of a signal inputted from the power divider. The at least one peaking amplifier amplifies power of a signal inputted from the power divider. The offset lines control a load impedance when the at least one peaking amplifier does not operate. When the at least one peaking amplifier does not operate, the Doherty circuit generates the load impedance of the carrier amplifier that is larger than twice a load impedance at the maximum output power of the carrier amplifier.

摘要： An apparatus and method for preventing falsification of a client screen is provided, in which a web server dynamically generates URIs and provides them to clients, thus preventing the falsification of client screens due to a web injection attack or a memory hacking attack. The apparatus includes a random web generation unit for converting an identical web page into random URIs that are randomly generated, at a request of a plurality of clients, generating different random web sources, and providing the different random web sources to the respective clients. A web falsification determination unit compares display web source eigenvalues respectively generated by the clients with respect to any one of the random web sources with a generative web source eigenvalue for the one of the random web sources, thus determining whether screens corresponding to the random web sources displayed on the respective clients have been falsified.
