Millimeter wave tile-type phased array antenna tr component

Abstract

The invention relates to a millimeter wave tile-type phased-array antenna TR module, and the invention aims at providing a TR module realization scheme with advantages of high reliability, low cost and high density integration for a millimeter wave frequency range high-power active phased-array antenna (APAA). The millimeter wave tile-type phased-array antenna TR module can be realized by the following scheme: a radio-frequency signal is fed from a radio-frequency vertical interconnection interface of a common port of the lower cavity bottom of the TR module, after the radio-frequency signal is performed the power distribution through a power divider mounting on the surface of a multi-layer circuit board and the like, the radio-frequency signal is fed in a multichannel amplitude-phase control chip connected with every transmit-receive channel, after the radio-frequency signal is performed the second power distribution by the multichannel amplitude-phase control chip, the amplitude-phase information of each channel radio-frequency signal is adjusted according to the state of the external control code and is outputted to a TR multi-function chip, the signal is amplified and outputted to the final power amplifier until saturation, the signal is outputted to a power switch, the emission access is gated, and the signal is transmitted to antenna radio-frequency vertical interconnection interfaces arranged on two ends of the cavity on the TR module; when the TR module receives a work, the radio-frequency signal passes through the TR module in a reverse direction.

technical field

[0001] The invention relates to a tile-type phased array antenna TR assembly, in particular to an active phased array antenna TR assembly of a transceiver half-duplex system working in the millimeter wave frequency band and a high-power millimeter wave tile with a single channel transmission power up to watt level Type TR component implementation technology. Background technique

[0002] At present, the two-dimensional active phased array antennas widely used mostly use brick structure TR components, which are characterized in that the component placement direction is perpendicular to the aperture of the phased array antenna, and the circuit adopts vertical integration and transverse assembly (LITA). Not limited to half-wavelength and can be extended according to design requirements. Therefore, this structure has low integration, relatively low design difficulty, high technology maturity, and easy circuit design and assembly; however, this structure limits t...
