Claim of US Patent No. 9,264,359

1. A method for transmission of a data signal from a transmitting device to at least one receiving device using a LINC amplifier
for signal amplification, the method comprising:
representing the data signal by two phase modulated signal components of constant amplitude in a first part of the LINC amplifier
located in the transmitting device;

converting the two phase modulated signal components of constant amplitude from electrical signals into optical signals in
at least one electro-optical converter located in the transmitting device;

transmitting both phase modulated signal components of constant amplitude from the transmitting device to the at least one
receiving device, with the two phase modulated signal components of constant amplitude being transmitted over two optical
connections from the transmitting device to the at least one receiving device;

converting the two phase modulated signal components of constant amplitude from optical signals into electrical signals in
at least one opto-electrical converter located in said at least one receiving device; and

amplifying and combining the two phase modulated signal components of constant amplitude in a second part of the LINC amplifier
that is located in said at least one receiving device.
