Voltage standing wave ratio (VSWR) is used to detect the working status of antenna feeder system, RF connector and all RF equipment connected to base station. Too high VSWR will lead to call drop […]
Overview of microwave RF passive components
Radio frequency (RF) filter/RF Combiner design continues to face electrical, mechanical and environmental challenges. For example, the system must meet the specified appearance size, the ambient temperature will affect the frequency response drift of the […]
1. IP protection level
Interpretation of IP code (meaning of “IP67” in filter industry – dust proof and waterproof IP level)
An […]
In Germany, no enterprise has become rich overnight and quickly […]
A good supplier is more important than a bank. When you go to the bank for a loan, you need to find a relationship with someone. You may not be able to get the loan. The interest is not low. […]
Due to the internal circuit characteristics, the input and output impedance of the high-frequency power amplifier tube deviates greatly from the characteristic impedance of the system transmission demand, so […]
Intermodulation(IM) or intermodulation distortion (IMD) is the amplitude modulation of signals containing two or more different frequencies, caused by nonlinearities or time variance in a system.
The electron tunneling effect and semiconductor behavior at […]
The rapid growth of mobile wireless data and 4G LTE networks has led to the growing demand for new frequency bands and combined frequency bands through carrier aggregation to accommodate wireless traffic. 3G network only uses about five frequency bands. […]
Radomes are large, dome-shaped structures that protect radar systems from bad weather conditions. The radomes allow electromagnetic signals to be received by the radar without distortion or attenuation.
Radar sensor is composed of a front end (RFE) (microwave […]
