1. Introduction The most attractive millimeter wave applications are mainly in the E band and V band. The E band corresponds to the frequency range of 60 GHz to 90 GHz. In this frequency band, due to the influence of atmospheric attenuation, only line-of-sight transmission can be used....
1. Introduction to Active Antennas 1 1. Introduction to Integrated Active Antennas With the development of mobile broadband networks, the data capacity requirements of site networks are growing rapidly. In the face of the growth of data capacity, the network needs to be more...
Abstract: This article is a selection guide for RF microwave power sensors. Based on the structure and test principle of modern power sensors, this article analyzes the advantages, disadvantages and application scenarios of various sensor technologies so that engineers can choose the appropriate...
As the 5G era progresses, smart terminal products, as the largest consumer market for broadband RF applications, face a series of development and verification issues. Among them, the increasingly smaller design space and electromagnetic radiation stray...
Development of RF Probes RF probes play an important role in almost every stage of the RF product life cycle: from technology development, model parameter extraction, design verification and debugging to small-scale...
Overview This article attempts to explain the view that RF testing and measurement should follow the principle of "how you use it, how I measure it". The principles of testing and measurement are roughly the same. For example, to measure a potential...
People have unlimited visions for 5G networks: for example, with higher network capacity and faster speeds, doctors can provide remote diagnosis for patients. At the same time, devices connected to the network in the Internet of Things (IoT) era will...
Take the thermal standing wave test of a 100W (50dBm) amplifier as an example. The coupling degree of the coupler is 20dB, the attenuator is 40dB, and the parameter selection rule is DUT output power - total loss = -10dBm circulator and...
For a long time, millimeter waves (frequency bands greater than 40 GHz) were mainly used in the military field, including various radars, satellite communications, etc., and civilian applications were limited to microwave point-to-point applications....
Are you still worried about not having high-end CAN test instruments and not being able to develop CAN bus? Today I will tell you: CAN card can also help you develop and test the automotive CAN bus....
In the PCIE3.0 consistency test, it is necessary to test the RX receiving end test and the RX EQ receiving end equalization test. Many engineers are not clear about the difference between the two. Let us explain...
1 Overview In a distributed control system based on remote communication, in order to enhance the compatibility and flexibility of the system, the remote communication function of the control node can be separated and handed over to the remote communication node....
In any actual mobile communication network, the signal quality of the signal transmitted between the base station and the mobile phone or other user equipment (UE) will be seriously degraded. This is because the signal transmission has...
Introduction Nowadays, wireless communication products based on radio frequency principle are everywhere, and their number is growing at an alarming rate. From cellular phones and wireless PDAs to WiFi-enabled laptops, Bluetooth...
The next generation of base station transmitters and receivers not only use multi-carrier (MC) technology for a single wireless standard, but also introduce multiple standards in a single transmitter path, which puts forward wider bandwidth requirements....
Introduction Fieldbus control system (FCS) will be the mainstream of automatic control system development in the new century and is a new generation of control system after DCS. Fieldbus is a necessity for the development of comprehensive automation....
The parameter commonly used in communication engineering to describe signal phase distortion - group delay (also known as envelope delay) is defined as: the slope of the characteristic phase shift of the network versus the frequency change curve. When the phase-frequency characteristic of the network is...
Positioning and related services have quickly found a wide range of applications and prospects in handheld devices, and users are increasingly relying on positioning services. How to accurately find your location, its technology...
