Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A transmitter comprising a Doherty amplifier and an antenna element (AN),
the Doherty amplifier comprising an input splitter, for splitting an input signal to a main amplifier having an output and to a phase delay connecting again to an auxiliary amplifier having an output,
wherein the antenna element is a dual-fed antenna element (AN) having first and second antenna parts (A1, A2),
the first antenna part (A1) having a first feed (F1),
the second antenna part (A2) having a second feed (F2),
the output of the main amplifier connecting to the first feed (F1) of the dual feed antenna element,
the output of the auxiliary amplifier connecting to the second feed (F2) of the dual feed antenna element,
wherein the dual-fed antenna element (AN, 43′) implements lossy two-port parameters of a combiner derivation such that the antenna element (AN, 43′) simultaneously is acting as a radiator, impedance matching network, and Doherty combiner.
