Product Description

Low insertion loss, high power capacity Waveguide high-pass filter 7.8 - 9GHz RF Microwave Filter

Product Description

 

Waveguide high-pass filters are broadband devices. Relying on structural designs such as stepped impedance and resonant cavities, and making use of the transmission characteristics of waveguides, they focus on suppressing the frequency bands at the lower end of the passband. They feature low insertion loss, high power capacity, and high out-of-band suppression, and are widely used in fields such as communication and radar. They can effectively filter out low-frequency interference and ensure the pure and stable transmission of high-frequency signals.

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.
