Definition:A Diplexer(duplexer) is a three-port passive radio frequency device that is a very common in communications, radar, and other sensing applications. Diplexer(duplexer) consists of two filters of different frequencies connected to an antenna. By using the frequency division function of high-pass, low-pass or band-pass filters, the same antenna or transmission line can use two signal ……

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 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……

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 ……

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……
