Abstract: An installation base includes a main body and a release member. The main body includes a first surface and a second surface on two opposite sides. The first surface is provided with a magnet piece. The release member is arranged on a second surface of the main body, and includes a pressing part, a pivoting part and an operating part. The pivoting part is pivotally connected to the main body in a first direction. The pressing part extends from the pivoting part in a second direction perpendicular to the first direction and protrudes from the main body, and a length of the pressing part in the second direction is greater than a thickness from the first surface to the second surface of the main body. The operating part extends from the pivoting part in the second direction toward a direction opposite to the pressing part.

Abstract: A scalable phased-array system for a wireless system includes: a plurality of transceivers, which are switched to form a transmitter mode and a receiver mode by means of time division duplexing (TDD), wherein each transceiver includes: a millimeter wave (mmWave) up-conversion circuit used to convert a baseband (BB) transmitter signal into an intermediate frequency (IF) transmitter signal; a power divider/combiner circuit used to divide the IF transmitter signal into a plurality of pairs of IF transmitter differential signals in the transmitter mode, and combine a plurality of pairs of BB receiver differential signals into a BB receiver signal in the receiver mode; and a beamforming circuit used to convert the pairs of the IF transmitter differential signals into a plurality of radio frequency (RF) transmitter signals in the transmitter mode, and convert a plurality of RF receiver signals into the pairs of the BB receiver differential signals in the receiver mode.
