Product Description

30.5 - 32GHz Copper Waveguide High - Pass Filter Signal Filter RF Microwave Filter

Product Description

Bandpass filter is a circuit that allows only certain frequencies to pass while effectively suppressing signals at other frequencies. A filter that passes frequency components in a certain frequency range but attenuates frequency components in other ranges to extremely high levels, as opposed to the concept of a band-stop filter.  Because of its signal selectivity, it is widely used in electronic design. In use, the filter does not completely attenuate all frequencies outside the desired frequency range, especially if there is a range outside the desired passband that is attenuated but not isolated.

FAQ

Regarding Frequency Bands

Q1: Can C - band filters be used for satellite TV?
A: C - band filters are commonly used in satellite communication and other scenarios. Although some satellite TV signals may be in the C - band, satellite TV mostly uses the Ku - band. So, C - band filters may not be suitable for satellite TV. It depends on the specific frequency band of the TV signal.

 

Q2: Where are X - band filters mainly used?
A: X - band filters are mostly applied in radar and aviation communication. For example, they are used in radar signal processing to ensure that the radar can accurately detect targets.

Regarding Materials

Q1: Are aluminum - made filters sturdy?
A: Aluminum - made filters are light - weight and cost - effective. Under normal usage environments and with proper operation, they can meet usage requirements and are relatively sturdy and durable.

 

Q2: Why are copper - made filters more expensive?
A: Copper - made filters are more expensive because copper has excellent electrical and thermal conductivity, performing well in scenarios with high - frequency signal transmission and high heat - dissipation requirements. Moreover, the cost of copper is relatively high.

Regarding Performance

Q1: What are the impacts of high insertion loss on signals?
A: High insertion loss means more energy loss when the signal passes through the filter. The signal will weaken, which may affect the quality and accuracy of signal reception by subsequent devices.

 

Q2: What happens if the voltage standing wave ratio is high?
A: A high voltage standing wave ratio indicates poor matching between the filter and the transmission line. There will be more signal reflection, reducing the transmission efficiency and potentially affecting the normal operation of the equipment.
