Abstract

The invention discloses a high-density and high-integration millimeter-wave tile-type phased array antenna T / R assembly, aiming to provide a T / R assembly design scheme with reliable performance, easy integration, and low profile. The present invention is realized through the following scheme: the radio frequency signal is directly fed in from the common end of the bottom cavity of the T / R assembly through the radio frequency coaxial connector, directly transitions to the T-shaped junction, and the single chip integrates power pre-amplification, power division network, amplitude Phase control, serial-to-parallel conversion, power management and digital control functions, cascading GaAs power amplifier chips corresponding to the number of channels to form a multi-channel 2.5-dimensional heterogeneous expandable sub-array unit, the low-frequency signal network directly controls the single chip of the T / R component and GaAs power amplifier to realize phase shift, amplitude attenuation and power amplification of multi-channel signals. The processed signal is sent to the upper end of the multi-layer circuit board of the T / R component through the vertical interconnection structure of coplanar waveguide to coaxial conversion. The filtering function layer, the filtered signal is finally sent to the microstrip patch antenna to transmit the radio frequency signal.

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...
