Description
Divimath SMA Bandpass Filter (5–6 GHz) 4 Pack
The Divimath SMA Bandpass Filter is designed to protect sensitive 5.8 GHz digital and analog video receivers from overload caused by nearby high-power RF transmitters operating outside the video band.
When high-power 900 MHz or 2.4 GHz control links (250 mW and higher) are operating close to goggles or video receivers, they can desensitize or overload the RF front end, even though the video system itself operates at 5.8 GHz. This results in reduced video range, dropouts, or unstable performance.
Installed inline between the antenna and the goggle or video receiver, the Divimath bandpass filter blocks out-of-band RF energy while allowing the 5–6 GHz video signal to pass cleanly. This enables high-power control links to operate in close proximity to video receivers without degrading video performance.
Key Features
- Designed for 5–6 GHz FPV and digital video systems
- Blocks high-power out-of-band RF interference (900 MHz and 2.4 GHz)
- Prevents receiver overload and desensitization
- Inline SMA installation between antenna and receiver
- Ideal for multi-radio setups with high-power control links
Installation Notes
- Installs directly between the antenna and goggle or video receiver
- Recommended: use 90-degree SMA adapters for a low-profile, compact goggle installation
- Helps reduce mechanical strain on SMA connectors while keeping the setup clean and secure
Performance Notes
- Passband insertion loss: approximately 0.5–0.75 dB across 5.3–5.95 GHz
- For maximum antenna performance, filters may be omitted when not required
- Gain loss can be offset by using a higher-gain antenna
Example antenna options for compensation:
- TrueRC X-Air MKII gain: 9.5–10.5 dBic
- TrueRC X2-Air MKII gain: 13 dBic
