Abstract
The invention discloses an integrated phase shifter including a power distribution network. The integrated phase shifter mainly comprises a metal cavity, a phase shifter PCB (Printed Circuit Board) base plate, a phase shifter sliding plate and an auxiliary part, wherein the metal cavity bears a phase shifter network, the phase shifter PCB base plate comprises the power distribution network, the phase shifter sliding plate is used for changing phases, and the auxiliary part is used for controlling the movement of the sliding plate. The length of each array subunit transmission line connected to an antenna can be changed due to left and right movement of the phase shift sliding plate, thus the phase change of each array subunit of the antenna can be controlled, and the purpose that a unit phase is continuously adjustable can be realized. When each unit phase is continuously adjustable, the power distribution network of each unit is combined with a fixed part of the phase shifter, thus the integrated phase shifter is smaller in volume and more convenient to produce; meanwhile, coupling transmission without direct contact is carried out on signal transmission between a moving part and the fixed part of the phase shifter, thus the generation of passive intermodulation and the frictional sparking phenomenon during moving can be restrained.
