- Low in-band attenuation and sharp cut-off characteristics. - Optimized for 1900 MHz video transmission (aviation mode) receivers, enabling effective filtering of out-of-band signals, reducing noise, and increasing dynamic range. - The inner ultrathin PCB provides excellent suppression of out-of-band remote-control signals, performing better than a bare PCB. - Shielded aluminum alloy housing minimizes interference and unwanted reactions outside the operating band, for stable, disturbance-free performance. - Material and construction: aluminum alloy housing; ultrathin internal PCB for compact, durable design; designed to enhance RF performance at 1900 MHz. - Compatibility and performance: tailored for 1900 MHz video transmission devices and aviation-mode receivers, with improved signal quality and stronger out-of-band rejection. Use scenarios - Aviation and airborne video link systems requiring clean RF performance and reduced interference in 1900 MHz bands. - UAVs, drones, and field video transmitters in environments with RF congestion, where robust out-of-band suppression improves image quality and link reliability. - RF test benches or control rooms where precise out-of-band rejection is needed to prevent remote-control or stray signals from affecting measurements or operations.
