Abstract

The invention discloses a high-density and high-integration millimeter-wave tile-type phased-array antenna T assembly and aims to provide a T assembly design scheme which is reliable in performance, easy to integrate and low in profile. According to the high-density and high-integration millimeter-wave tile-type phased-array antenna T assembly provided by the technical schemes of the inventio, radio frequency signals are directly fed from the common end of the bottom of the lower cavity of the T assembly through a radio frequency coaxial connector; direct transition to a T-junction is realized; each chip integrates the functions of power pre-amplification, a power division network, amplitude-phase control, serial-parallel conversion, power source management and digital control; GaAs poweramplifier chips with corresponding quantities of channels are cascaded to form a multi-channel 2.5-dimensional heterogeneous extensible subarray unit; a low-frequency signal network directly controlsthe chips and the GaAs power amplifiers of the T assembly; multiple paths of signals are subjected to phase shift, amplitude attenuation and power amplification; the processed signals are sent to thefiltering function layer of the upper end multi-layer circuit board of the T assembly through a coplanar waveguide-to-coaxial conversion vertical interconnection structure; the filtered signals are finally sent to a microstrip patch antenna, so that radio frequency signals are transmitted.

Description

technical field [0001] The invention relates to a high-density and high-integration millimeter-wave tile-type phased antenna T / R assembly (abbreviated as T assembly) component realization technology when the millimeter-wave transceiver co-aperture phased array antenna works in full duplex. Background technique [0002] With the continuous development of device and process integration technology, and the continuous enrichment of electronic equipment functions in the detection and communication fields, the application of millimeter-wave phased arrays is becoming more and more extensive. The active phased array antenna is a commonly used antenna form. As the core module of the active phased array antenna, each channel integrates functions such as power amplification, phase shifting, and attenuation. In addition to functions such as RF amplification, phase shifting, and attenuation, a complete T / R component generally includes other control functions such as serial-to-parallel si...
