Description

The RAKwireless Outdoor Cavity Band-Pass Filter is an RF accessory that boosts LoRaWAN gateway performance in high-interference environments. It allows only the target LoRa band to pass while attenuating out-of-band signals such as LTE, 5G, radar, and industrial noise — so your gateway hears genuine LoRa traffic, not the surrounding RF clutter.

Built on a high-Q resonant cavity design, this EU868 (863–870 MHz) model isolates the band with >70 dB out-of-band rejection and just <2.5 dB insertion loss, keeping LoRa signal strength intact. Standard N-Female ports and an IP67 body make it a drop-in upgrade for urban and industrial outdoor deployments.

Core Capabilities

High Out-of-Band Rejection A high-Q resonant cavity isolates the EU868 band with >70 dB of out-of-band rejection, suppressing LTE, 5G, radar, and industrial noise that would otherwise desensitise the gateway.
Low Insertion Loss Insertion loss of <2.5 dB across 863–870 MHz, with VSWR <1.25, preserves LoRa signal strength so the filtering doesn't cost you range.
Easy Inline Integration Standard N-Female ports connect the gateway (Port 1) and antenna (Port 2) with no adapters, plus a ground pad for ESD and surge protection.
Rugged Outdoor Build An IP67 cavity body rated −40 °C to +65 °C and up to 100 W input power is built for permanent tower- and rooftop-mounted gateway sites.

Typical Applications

Dense Urban Sites: Reject strong LTE/5G signals from co-located cellular equipment that would otherwise desensitise a rooftop LoRaWAN gateway.
Industrial Environments: Cut radar, machinery, and broadband RF noise to keep uplink reception stable on factory and plant deployments.
Coverage & Sensitivity Recovery: Restore weak-signal reception and reduce packet loss at sites suffering from out-of-band interference.
Outdoor Tower & Rooftop Gateways: An IP67 inline filter for permanent installations alongside the antenna feed.

Technical Integration

Key points for fitting the filter into your RF path:

RF path: Installs inline on the antenna feed — N-Female Port 1 to the gateway, N-Female Port 2 to the antenna, no adapters required.
Pass band & loss: 863–870 MHz (EU868) with insertion loss <2.5 dB and VSWR <1.25.
Rejection: >70 dB out-of-band attenuation against LTE, 5G, radar, and industrial noise (the wider product family reaches >75 dB).
RF ratings: Input power up to 100 W and 3rd-order intermodulation products <−150 dBm for clean, high-power links.
Grounding & environment: Bond the ground pad to earth (strongly recommended for ESD/surge); IP67, −40 °C to +65 °C, 228 × 164.6 × 51.5 mm, 1.5 kg.
Setup help: For band selection (other regional variants are available) or interference troubleshooting, contact the shopioT technical team.

Note: an RF coaxial cable to the gateway and antenna, and earth-grounding hardware, are required and sold separately.

Frequently Asked Questions

What does this filter do?

It's a high-Q cavity band-pass filter that passes the LoRa band while rejecting out-of-band LTE, 5G, radar, and industrial noise — improving gateway reception and reducing packet loss at high-interference sites.

Which band is this version?

EU868 (863–870 MHz). The product family also offers US915, IN865, AU915, KR920, AS923-1/2/3/4, and CN470 variants — contact us if you need a different band.

How much interference does it reject, and at what cost to signal?

More than 70 dB of out-of-band rejection with under 2.5 dB insertion loss and VSWR <1.25, so it cuts interference while preserving LoRa signal strength.

How is it installed?

Inline on the antenna feed: connect Port 1 (N-Female) to the gateway and Port 2 (N-Female) to the antenna, then bond the ground pad to a low-impedance earth.

Why should I ground it?

The ground pad provides ESD and surge protection and is strongly recommended. For full lightning protection, pair it with a dedicated surge arrestor.

Is it suitable for outdoor use?

Yes — it's IP67-rated and operates from −40 °C to +65 °C, built for permanent tower and rooftop installation.
