Problems solved by technology

In order to prevent the components from being interfered by the background, you can increase the attenuator or reduce the front-end gain at the receiving front end, but this method will increase the noise figure of the components and reduce the sensitivity of the radar
The conventional design method can increase the attenuator or reduce the gain of the front end to improve the anti-interference ability of the component, but it will cause the deterioration of the receiving sensitivity

Embodiment Construction

[0013] Component principle and layout such as figure 1 and figure 2 As shown, the overall layout of the components adopts the scheme that the cold plate is placed in the middle of the box and the modules are installed separately on both sides. One frequency mixing module and eight front-end transceiver modules are installed on the front of the box, and the power distribution circuit board and digital board are installed on the On the back of the box, the power divider is hidden under the digital board, next to the water channel. The digital board is installed in the reverse way, that is, the side of the board where the device is placed is placed close to the cold plate, which is good for heat dissipation and improves the utilization rate of space size.

[0014] The block diagram of the front-end transceiver module is as follows: image 3 As shown, in order to reduce the size of the module, phase shifters and attenuators are shared by multiple channels. The frequency mixing...

Abstract

The invention relates to a design method for improving the anti-interference ability and realizing miniaturization of a broadband transceiver component. A module is modular designed, a multi-die carrier board and a multifunctional bare chip are used by a radio frequency module, a micro-assembly process is employed for assembly, and the size and weight of the module are reduced. The size of the module is further reduced by means of an embedded design of a power divider and reversed mounting of a digital circuit board (shown in the drawings). The anti-interference ability of the module is improved by optimizing distribution of link parameters, improving the device design, reducing the gain of a front-end transceiver module, increasing a 1dB compression point of a frequency mixing module, adding a switching filter bank, etc.

Description

technical field [0001] The invention belongs to the design technology of TR components of an active phased array radar system. Background technique [0002] With the increasing use of phased array radars, higher requirements are put forward for the lightweight and miniaturization of radars. In an integrated radio frequency system including multiple types of radars, the anti-interference ability of radars is also a measure of the performance of radars. Poor important indicator. As an important part of phased array radar, the transceiver components are closely related to the area array in terms of performance, weight and volume. [0003] Because communication and wireless network signals are mainly concentrated in the L and S bands, when the radar works in this frequency band, it is strongly interfered by space communication and wireless network signals. Therefore, it is also very important to improve the anti-interference ability of components and realize signal transmission...
