High-integration brick type TR assembly

Abstract

The invention provides a high-integration brick type TR assembly. The high-integration brick type TR assembly comprises a shell, a radio frequency circuit board, an inner cover plate and an outer cover plate, wherein an installation cavity is formed in one end surface of the shell, a radio frequency output end connector and a low-frequency connector are arranged on one side wall of the installation cavity in a penetrating way, radio frequency antenna end connectors are arranged on the opposite side wall of the installation cavity in a penetrating way, and 24 radio frequency antenna end connectors are arranged; the radio frequency circuit board is arranged in the installation cavity, radio frequency and digital components are arranged on the front surface of the radio frequency circuit board, radio frequency microstrip lines are arranged on the back surface of the radio frequency circuit board, the radio frequency microstrip lines on the front surface and the back surface are connectedby a printed board vertical interconnection through hole, the radio frequency output end connector, the low-frequency connector and the radio frequency antenna end connectors are all connected to theradio frequency circuit board, and the radio frequency circuit board is provided with multifunctional chips and power supply modulation modules corresponding to the radio frequency antenna end connectors; a shielding cavity is formed in the bottom surface of the inner cover plate, the inner cover plate is arranged on the radio frequency circuit board, and the multifunctional chips are arranged inthe shielding cavity; and the outer cover plate is used for sealing the installation cavity. By a multi-channel integrated design, the volume of the brick type TR assembly is reduced, the sealing performance is better, and detection and debugging are facilitated.

Description

technical field [0001] The invention belongs to the technical fields of radar, telemetry and communication, and in particular relates to a highly integrated brick-type TR assembly. Background technique [0002] With the development of the times, active phased array radar has been more and more widely used due to its unique performance indicators, high integration and weight advantages, and has a tendency to completely replace traditional radar. The TR component is the core component of the active phased array radar, and its performance index and volume directly determine the performance of the active phased array radar equipment. Based on this, under the premise of ensuring the electrical performance index, TR components are gradually developing towards miniaturization and integration. At present, traditional TR components usually integrate a small number of channels, and the function of the channel chip is relatively single, resulting in high cost of TR components, low deg...

AI Technical Summary

Problems solved by technology

At present, traditional TR components usually integrate a small number of channels, and the function of the channel chip is relatively single, resulting in high cost of TR components, low degree of integration, and poor consistency of batch production indicators.

[0003] At present, the multi-channel integration of TR components is mainly limited by the relatively single function of the chip, and the number of chips used in a single channel of the component is large.

As a result, during multi-channel integration, the indicators of each channel are quite different, the consistency of batch production indicators is poor, the workload of debugging is large, and the volume has no obvious advantages compared with traditional TR components. The above factors are the main reasons why TR components cannot be highly integrated.
