Today's portable medical devices allow patients to diagnose and treat themselves, move around freely, and even use the devices when they are out and about. To achieve the "easy to carry" feature, po...[Details]

As the whole equipment is constantly miniaturized and power-saving, low-power-consumption low-dropout linear regulators (LDO) are becoming the mainstream of the linear regulator market for switching p...[Details]

The small size and low cost of home appliance control boards mean that high-cost materials will not be used in the circuit to solve the electromagnetic interference problem. The interference of hom...[Details]

Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[Details]

Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communications since the advent of digital communications. Many new wireless commun...[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]

Overview In recent years, the vigorous development of integrated circuits has created a huge space for the research and application of digital circuits. FPGA has low power consumption, high re...[Details]

Introduction The MAX2116 P1db data is measured at specific combinations of RF and baseband gain over the adjustable range of these two gains. These data can be used to select gain control se...[Details]

1. Basic circuit characteristics of power amplifier The basic circuit of the complementary symmetrical OTL power amplifier is shown in Figure ①. Among them: C1 is the signal input coupling ele...[Details]

In the process of RF transceiver application, adjusting the processing gain (PG) of the direct sequence spread spectrum communication system (DSSS) can obtain excellent anti-noise performance, whic...[Details]

This paper introduces the technology and application of optical transceiver modules and digital non-volatile variable resistors in optical communication networks, and focuses on the design and appl...[Details]

Portable products are generally powered by batteries. Due to cost and size considerations, there is a trend to reduce the number and size of batteries used in design. If the number of batteries is ...[Details]

1 Introduction In many communication systems, the base station usually sends a training sequence for the terminal to synchronize with the system. The synchronization here includes time syn...[Details]

1. Introduction Most of the existing heaters use traditional devices such as electric heating tubes and electric heating wires for heating. The outer shell of the electric heating tube is a ...[Details]

"Where am I? Where am I going? Where is he/she? How far is he/she from me?..." Do you often have such questions like me? In fact, who can deny that these are questions that we often think about, ev...[Details]
