Basic Introduction to RF Connector30 October 2025
The RF connector is a component that connects to the coaxial cable, microstrip line or other RF transmission line to realize the electrical connection and separation of the transmission line, or to transfer different types of transmission lines. It belongs to the electromechanical integration product and acts as a bridge.

Hello everyone, welcome to the new post today.
Japan's Three-Stage Strategy to Revive the Semiconductor Industry01 April 2022
Continuing chip shortages and the high risk of disruptions in the semiconductor supply chain remain major challenges for governments around the world, and Japan is under tremendous pressure to find solutions to revitalize the semiconductor industry. In recent years, the global market share of Japanese semiconductor companies has been declining, from 50.3% in 1988 to less than 10%. To develop an effective industry revitalization strategy, the Japanese government and domestic semiconductor companies are now reflecting on why Japan's semiconductor industry has been losing ground to foreign competitors in the global market.
What is a Semiconductor?22 October 2025
Semiconductor refers to a material whose conductivity is between a conductor and an insulator at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting applications, and high-power power conversion.
What is An Optoisolator?09 January 2021
An optoisolator, also called optical coupler, optocoupler, and opto-isolator, is a device that encapsulates the infrared light-emitting device, the infrared light receiving device, and the signal processing circuit in the same tube socket.
Function and Application of Laser Sensors28 October 2025
Laser sensors are sensors that use laser technology for measurement. It consists of laser, laser detector and measuring circuit. The laser sensor is a new type of measuring instrument.
The History of Microscope21 October 2021
Hello, everyone. I am Rose. Today I will show you the history of microscopes. The microscope is used to magnify tiny objects into instruments that can be seen by human eyes. Microscopes are divided into optical microscopes and electron microscopes.
What is Sequential Logic?15 October 2020
Sequential logic is an important part of digital logic circuit, which is mainly composed of storage circuit and combinational logic circuit. Sequential logic is also called sequential logic circuit. It is different from other circuits that we are familiar with. Its output state at any time is determined by the input signal and the original state of the circuit at that time, and its state is mainly memorized and represented by the storage circuit.
Switch-mode Power Supply Basics14 December 2020
Switched-mode Power Supply (SMPS), also known as switching converter, is a high-frequency electric energy conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture.
What is Gallium Nitride(GaN)?19 January 2021
GaN is a very stable compound and a hard high melting point material with a melting point of about 1700°C. GaN has a high degree of ionization, which is the highest (0.5 or 0.43) among III-V compounds. Under atmospheric pressure, GaN crystals generally have a hexagonal wurtzite structure. It has 4 atoms in a cell, and the atomic volume is about half of GaAs. Because of its high hardness, it is also a good coating protection material.
What is Oscilloscope?24 September 2021
An oscilloscope, formerly known as an oscillograph, is an instrument that graphically displays electrical signals and shows how those signals change over time. This article will introduce it in four aspects.
What is Graphics Processing Unit (GPU)?18 October 2021
Hello everyone, I am Rose. Welcome back to the new post today. The graphics processing unit (GPU), also known as the visual processor, display core, or display chip, is a type of microprocessor that specializes in image processing on personal computers, workstations, gaming consoles, and mobile devices (such as tablets and smartphones). After reading this article, you will have a clear understanding of GPU.
