The AL4205 is a high-performance wireless data transmission module purpose-built for long-range analog signal links that demand reliability over raw output power. Operating across the 3.7–4.3 GHz band — including the upper 4.2–4.3 GHz segment — it delivers up to 5 W output power in multiple adjustable levels, making it the preferred choice where regulatory compliance, spectral flexibility, and efficient power use matter more than maximum transmit power.
Unlike high-power FPV-oriented transmitters, the AL4205 is optimized for sustained, low-to-medium power operation. Its PLL frequency control enables precise channel selection and stable frequency locking, while efficient power calibration keeps output consistent across the band and across voltage and temperature variations. The aluminum alloy cooling structure, paired with a high-speed centrifugal fan, supports reliable continuous duty in enclosed industrial enclosures and remote outdoor installations — environments where heat buildup and unattended operation are the primary concerns.
With its compact footprint, wide voltage input range, and protocol-based parameter adjustment, the AL4205 integrates cleanly into industrial wireless communication systems, remote telemetry and sensor links, and customized transmission systems requiring configurable, repeatable performance rather than short-burst peak power.
