Hong Kong Resistor Manufacturing Co., Ltd. was established in 1985 as a Hong Kong-invested enterprise. Headquartered in Hong Kong, it has two production bases in mainland China, located in Dongguan City, Guangdong Province and Yiyang City, Hunan Province. The testing standards of our resistor products follow the industrial specification standard of Japan JISC-5202.
In the previous experiments, we verified that we can read and write AT commands from the UART1 port of the NB-IoT module . But in fact, we hope to miniaturize this environment (the smaller the better)...

In a radar or radio receiver, sensitive low-noise amplifiers (LNAs) are bound to fail when subjected to large input signals. So, what is the solution?
We can protect sensitive components by using a re...
For many of us, the standard default router provided by our internet service provider (ISP) when we signed up for broadband is more than adequate.However, over the past decade, mobile technology — inc...
A very critical indicator of the switching power supply is ripple, which is mainly caused by the switching conversion method. The existence of ripple will also affect the work of subsequent circuits, ...
