Implementation of "phase shifting" Due to the direct correlation between the "phase" of each signal and the emission direction and stacking strength of the signal, the "phase shifting" function is a very important functional module in phased array systems. In modern phased array systems, the phase shifting function is usually achieved by a phase shifter [...]
Interconnection of antennas and RF chips At present, domestic and foreign chip manufacturers have launched mass-produced 24GHz RF chips into the market. In the zero intermediate frequency radar architecture, the pins of the RF chips are directly connected to the microstrip transceiver antenna ports. When using a hybrid form of antenna board (high-frequency board)+several layers [...]
Laying copper in PCB design is a very important aspect of circuit board design. What is PCB copper laying? It means filling the idle space on the PCB without wiring with solid copper. The significance of laying copper is to reduce the impedance of the ground wire and improve its anti-interference ability; Reduce voltage drop, [...]
The circuit materials of printed circuit boards (PCBs) are key building blocks for radio frequency (RF)/microwave circuits - essentially the starting point of these circuits. PCB materials come in many different forms, and the selection of materials largely depends on the requirements of the intended application. For example, when entering extreme situations in military environments, [...]
Inductors - also known as chokes, reactors, and dynamic reactors. Together with capacitors and resistors, they are known as the three major passive components, and relay containers and resistors have rapidly developed into chip based components. Basic Principles Self induction phenomenon: electromagnetic induction phenomenon produced when the current flowing through the conductor itself changes. The [...]
Hello everyone, today I'm going to talk about an article about circuit board principles. Now let's take a look! 1. The working principle of a circuit board is to use board based insulation materials to isolate the copper foil conductive layer on the surface, allowing current to flow through various components along a pre designed [...]
In the process of circuit design, application engineers often overlook the layout of printed circuit boards (PCBs). The common problem encountered is that the schematic of the circuit is correct, but it does not work or only operates at low performance. In this blog post, I will introduce you how to correctly lay out the [...]
CINNO Research industry information, according to the Japanese media Nihon Keizai Shimbun, Japan Tuozhida Wire Co., Ltd. cooperates with Israel's Copprint Technologies Ltd. to develop copper nano ink that can easily print circuit boards. According to the previous method, the printed circuit needs to be pressurized and sintered in special gases such as hydrogen. However, [...]
