Factory Cheap Hot China Solid State High Power Pulse Amplifier for EMI/Rfi, Lab, Pulse, Radar Applications

Short Description:

Waveguide filter is a kind of transmission line filter. Generally, waveguide filter is composed of discontinuities and transmission line segments. Both can be equivalent to corresponding lumped parameter elements and circuits, waveguide discontinuities provide equivalent reactance, transmission line segments, equivalent resonators and so on.

When designing the filter, we usually need to comprehensively consider the customer’s actual use environment, customer performance requirements (such as filter volume, loss, out of band frequency, suppression system and power capacity) and processing technology to achieve the premium effect of the filter.

Features

Passive filter, also known as LC filter, is a filter circuit composed of a combination of inductance, capacitance and resistance, which can filter out one or more harmonics. The most common and easy to use passive filter structure is to connect the inductance and capacitance in series, which can form a low impedance bypass for the main harmonics (3, 5 and 7); Single tuned filter, double tuned filter and high pass filter are all passive filters.

The passive filter is composed of capacitor string reactance.

According to the harmonic condition of the system, for example, there are 5th harmonics, and the harmonic frequency is 250Hz.

At this time, the capacitance and reactance of the passive filter are matched, and they resonate at the frequency of 250Hz. Because the total impedance of the two resonates in series is 0, which is commonly known as the low impedance loop, at this time, all the 5th harmonic will flow into the passive filter to achieve the filtering effect.

Due to process reasons, generally speaking, the passive filter can achieve about 245-250Hz, and the filtering effect can reach more than 80%.

It has good frequency selection and filtering functions in circuits and electronic high-frequency systems, and can suppress useless signals and noise outside the frequency band.

It is used for aviation, aerospace, radar, communication, electronic countermeasure, radio and television and various electronic test equipment.

When using, pay attention to the good grounding of the shell, otherwise it will affect the out of band suppression and flatness index.
