Principle of vector network analyzer
The vector network analyzer has many functions and is known as the “king of instruments”. It is a multimeter in the field of radio frequency and microwave, and a test equipment for electromagnetic wave energy. Early network analyzers only measured amplitude. These scalar network analy...Read more -
What is the difference between 4G and 5G? When will the 6G network be launched?
Since 2020, the fifth generation (5G) wireless communication network has been deployed on a large scale worldwide, and more key capabilities are in the process of standardization, such as large-scale connection, high reliability and guaranteed low latency. The three major application scenarios o...Read more -
N-type connector
N-type connector N-type connector is one of the most widely used connectors because of its solid structure, which is often used in harsh working environments or in test fields that require repeated plugging. The working frequency of standard N-type connector is 11GHz as specified in MIL-C-39012,...Read more -
Structure and working principle of coaxial cable
As we all know, coaxial cable is a broadband transmission line with low loss and high isolation. The coaxial cable consists of two concentric cylindrical conductors separated by dielectric gaskets. Capacitance and inductance distributed along the coaxial line will generate distributed impedance i...Read more -
Details of RF coaxial SMA connector
SMA connector is a widely used semi precision subminiature RF and microwave connector, especially suitable for RF connection in electronic systems with frequencies up to 18 GHz or even higher. SMA connectors have many forms, male, female, straight, right angle, diaphragm fittings, etc., which can...Read more -
Performance parameters of RF switch
RF and microwave switches can send signals efficiently in the transmission path. The functions of these switches can be characterized by four basic electrical parameters. Although several parameters are related to the performance of RF and microwave switches, the followi...Read more -
How to select coaxial switches?
Coaxial switch is a passive electromechanical relay used to switch RF signals from one channel to another. These switches are widely used in signal routing situations that require high frequency, high power and high RF performance. It is also often used in RF test system...Read more -
Automatic test system for optical modules
It is understood that other optical module manufacturers use virtual instrument technology to realize the automatic testing process of various performance parameters of optical modules. This method requires the use of a large number of expensive instruments, which are co...Read more -
