FAQ
- What are the typical application scenarios for this 8-18GHz filter?
- This filter is specifically designed for IBS (In-Building Solutions) and DAS (Distributed Antenna Systems) that operate in high-frequency microwave bands. It is also ideal for satellite communications, radar signal conditioning, and laboratory testing where 8-18GHz frequency selection is required.
- Why does this model use 2.92mm Female connectors instead of SMA?
- The 2.92mm connector (also known as the K connector) is designed for high-frequency performance up to 40GHz. It offers superior mechanical reliability and lower VSWR at 18GHz compared to standard SMA connectors, ensuring a more stable microwave link.
- How effective is the out-of-band suppression?
- The filter provides steep rejection of ≥40dB from DC to 7GHz, effectively blocking interference from cellular and Wi-Fi bands. It also maintains ≥30dB rejection in the 31-35GHz range to suppress high-frequency harmonics and millimeter-wave interference.
- Can this filter withstand harsh environmental conditions?
- Yes, it is built with an operating range of -40 to +60°C and finished with protective green-white paint. This makes it suitable for deployment in unconditioned equipment rooms and various industrial communication environments.
- What does a VSWR of ≤1.8:1 mean for my system?
- A VSWR of ≤1.8:1 ensures that signal reflections are kept to a minimum across this ultra-wide 10GHz bandwidth. This protects sensitive microwave transmitters and ensures maximum power efficiency throughout the signal path.
