What are the differences between Ka-band and Ku-band in satellite communications?

Definition: The Ka-band with frequency range 26.5 ~ 40GHz, is part of the microwave band of the electromagnetic spectrum. In other words, the band is directly above the K-band.The Ka-band is also known as the 30/20 GHz band and is commonly used for satellite communications.26.5~40GHz coaxial circulatorThe disadvantage of the Ka-band is that the rain attenuation is relatively high, and the requirem……

Working frequency of Radar: Select carefully during design

Working frequency of Radar The core of radar working principle is that the radar transmits electromagnetic wave of a certain frequency, receives the echo reflected by the target, and determines some states of the target according to the echo. The frequency of electromagnetic wave emitted by radar is its working frequency. The radar frequency band refers to the frequency range in which th……

Millimeter Wave and its applications

Definition:Millimeter wave (Abbr.: mmWave): The electromagnetic wave with a wavelength of 1 ~ 10 mm is called millimeter wave. It is in the overlapping wavelength range of microwave and far-infrared waves. Therefore, it has the characteristics of two kinds of spectrum.There is no precise definition of millimeter wave frequency band, usually the electromagnetic wave in the frequency domain of 26.5 ……

What should we pay attention to when use the RF Isolators/circulators?

1. Please note the direction of isolator and circulator is very important.The reverse operation is not allowed, which would cause the malfunction or damage eventually.2. It is required to use non-inductive stainless screws, and make sure the parts are well grounded.3. RF Isolators and circulators have magnetic property, please keep away from ferromagnetic substances during operation.For example, t……

What is Waveguide to Coaxial Adapter?

In the field of radio frequency and microwave, in addition to the transmission of wireless signals, most of the scenarios still need to use transmission lines for signal transmission. Among them, coaxial cables and waveguides are widely used.In order to be used in various occasions, these two transmission lines are sometimes connected to each other, which requires a waveguide to coaxial adapter (o……
