The invention relates to a multi-channel highly integrated surface-mounted TR component control chip, including a digital control module, a level conversion module, a power modulation module, a negative grid voltage digital-to-analog converter and a negative grid voltage analogue integrated on a single chip. Switch module; the digital control module is used to output the wave position control signals of five channels in parallel, and output after level conversion by the level conversion module, respectively control the power amplifier of the TR assembly, the transmitting drive amplifier, the receiving Amplitude, phase and sending and receiving of the drive amplifier, low noise amplifier and common branch drive amplifier; the power modulation module is used to output five-way drain voltage pulse modulation signals; the negative grid voltage digital-to-analog converter is used to generate five-way gate voltage bias signal. The invention also provides a TR assembly and an active phased array antenna system. The invention greatly improves the integration degree of the power supply and control circuit of the TR component by integrating the power supply and control of five channels into a single chip.
Description
technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a multi-channel highly integrated surface-mounted TR component control chip, a TR component and an active phased array antenna system. Background technique [0002] With the rapid development of 5G millimeter wave, radar and other industries, active phased array antennas are widely used as an indispensable part, among which TR components are the key components to realize the functions of beam transmission and reception switching and phase shift attenuation for a single channel . A two-dimensional active phased array antenna usually contains hundreds to tens of thousands of TR components, which account for most of the cost of the entire radar. Therefore, the miniaturization and high integration of the internal chip of the TR module is the core method to reduce the volume and weight cost of the module and improve the reliability. [0003] The TR module contains two pa...
