Frequently Asked Questions
- Q1: What are the primary applications for the 863-873MHz and 1085-1095MHz cavity filters?
- A: The 863-873MHz range is commonly used for European IoT/LPWAN (like LoRaWAN) and RFID applications. The 1085-1095MHz filter is often utilized in aviation and aerospace applications, such as ADS-B signal processing, to ensure clear communication without interference.
- Q2: What makes a "Cavity" filter superior to other passive filter types?
- A: Cavity filters offer a much higher Q factor, which results in sharper roll-off and lower Insertion Loss (≤1.0dB). They are also capable of handling higher power levels (30W and above) and provide excellent temperature stability, making them more reliable for base station environments.
- Q3: How does the "High Aseismatic Capability" benefit the installation?
- A: High aseismatic capability means the internal cavity structures are built to withstand significant mechanical vibrations and shocks. This is crucial for equipment installed on towers, poles, or near heavy machinery where vibrations could otherwise shift the frequency response of the filter.
- Q4: Why is a 40dB attenuation level important for out-of-band signals?
- A: Attenuation of ≥40dB ensures that signals outside your operating band are suppressed by 10,000 times. This prevents interference from neighboring cellular bands or high-frequency noise from desensitizing your receiver, thereby maintaining maximum system sensitivity.
- Q5: Can Maniron provide filters with customized frequency bands or connector types?
- A: Yes. We offer comprehensive custom design services. Whether you need a different passband frequency, higher attenuation at specific points, or different connectors like SMA or 4.3-10, our engineering team can provide a tailored solution that meets ROHS standards.
