Current collapse effect in HEMTs
I believe everyone is familiar with the polarization effect in GaN materials and the generation principle of two-dimensional electron gas (2DEG). Because 2DEG has an u...
1. The fewer the alternations between the lead layers of the high-frequency circuit device pins, the better. That is, the fewer vias are used in the component connection process, the better. According...
To prove how capable I am, I drew a circuit board diagram by myself, and then I did it again using automatic wiring. By comparison, I realized that I was really stupid! Even if I memorized the PCB dia...
These days, I am still watching "Dwelling Narrowness" in an orderly manner. I feel that Su Chun and Xiao Bei are both unmarriable, but that is another topic. I saw Haiping getting angry with her manag...
The U.S. Food and Drug Administration (FDA) points out that home health care is the fastest growing area in the medical device industry. Driven by the increase in average life expectancy, the increasi...[Details]

TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
Today, various applications such as consumption, computers, industry and instruments urgently need compact and effective power solutions, while also meeting the requirements of efficiency, fast tra...[Details]
1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
Industrial control
often requires multi-channel fault detection and multi-channel command control (this multi-task setting is very common). A single CPU chip is difficult to directly complete ...[Details]
1 Introduction to suction laminating machine
Suction laminating machine is a kind of woodworking machinery, which can realize the laminating function of wood boards and other materials. It i...[Details]
The full name of RFID is Radio Frequency Identification, which uses radio frequency to realize data transmission between programmable controller (PLC) or microcomputer (PC) and identification, ther...[Details]
The growing global interest in green power has added new variables to the design of power supplies and power adapters. Designers must not only traditionally consider the design specifications requi...[Details]
As process nodes and die sizes continue to shrink, the number of consumer electronic products using flip-chip packaged IC devices is increasing. However, flip-chip packaging manufacturing rules hav...[Details]
The four-element infrared detector uses photosensitive elements, and the alarm is triggered only when each detector detects a signal. It has stronger anti-false alarm capability and better detectio...[Details]
