Abstract

A transmitter or receiver including at least one radio-frequency (RF) chain. The RF chain including an array of transmitting elements, each transmitting element includes a band-pass filter and an antenna connected in series for transmitting an analog signal using a beamforming with an angle of departure (AOD) defined by phase shifts of analog signals received by different transmitting elements within the array. A phase shifter to shift a phase of an input signal. A variable gain amplifier (VGA) to change an amplitude of the input signal. A switcher to connect the phase shifter and the VGA to each transmitting element in the array. Wherein at most one transmitting element is connected to the phase shifter and the VGA at a given point of time, such that the switcher is a single-pole-M-throw (SPMT) analog switch. A controller to control the phase shifter, the VGA and the switcher.
