Embodiment Construction

[0034] The electromagnetic compatibility design method of the radio frequency module provided by the present invention mainly elaborates the electromagnetic compatibility design method from four aspects of circuit board design, structural shielding design, power filter and routing design, and radio frequency hybrid circuit design. The present invention will be further described in detail below.

[0035] 1. Circuit board design: Digital circuits and analog circuits should be laid out separately, especially as far as possible from low-level analog circuits to avoid common impedance problems. The high-speed circuit, medium-speed circuit and low-speed circuit should be laid out separately, so that they can use their own areas to make the high-frequency current traces the shortest.

[0036] Ground wiring rules: The ground grid is especially suitable for digital circuits. For digital circuits, when wiring circuit boards, the ground grid should be laid out first, and then the signal ...

Abstract

The invention discloses a radio frequency module electromagnetic compatibility design method comprising circuit board design, structural shielding design, power supply filtering and wiring design and radio frequency hybrid circuit design. The characteristics of various components are considered, and various components are arranged in a classified way so that common impedance coupling can be avoided; and the output signals of various lines are considered for reasonable wiring, and shielding is additionally arranged for the lines and the circuit modules having special requirements so that the mutual interference between the circuits can be reduced. The radio frequency module electromagnetic compatibility design method is applied to the field of the radar simulator, radio frequency semi-physical simulation and electronic countermeasure so that the weight and the size of electronic equipment can be reduced, the anti-interference capability of the electronic equipment can be enhanced and the product stability and the work efficiency can be enhanced.

Description

technical field [0001] The invention relates to an electromagnetic compatibility design method of a radio frequency module. Background technique [0002] The design of electronic equipment is not simply to connect the signal lines correctly. Electromagnetic compatibility on radio frequency electronic equipment has become a factor that must be considered. For conventional radio frequency circuits, because of the abundance of volume and space, the electromagnetic compatibility problem on radio frequency electronic equipment is not so much severe. With the rapid development of science and technology and the strict requirements on the weight and volume of equipment on airborne and spaceborne equipment, all kinds of electronic products are pursuing lightness, thinness and shortness, and the manufacturing process of electronic equipment is also tending to be reduced and multi-layer boards. It has become an important technology for radio frequency circuit design to carry out elect...
