Title:
FEED-FORWARD AMPLIFIER AND ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/150454
Kind Code:
A1
Abstract:
A feed-forward amplifier comprises a phase shifter (19) for adjusting the phase of another modulated transmission signal distributed by a directional distributor (12), and a directional combiner (21) for combining the modulated transmission signal the phase of which has been adjusted by the phase shifter (19) with one modulated transmission signal distributed by the directional distributor (17), wherein the directional combiner (21) outputs a combined modulated transmission signal obtained by combining the modulated transmission signals to an error amplification circuit (22).
