High power output: supports 15W (42dBm@28V), up to 20W (43dBm), meeting high-power requirements. Wideband working range: 86835MHz (833MHz-903MHz), compatible with multiple wireless communication standards (such as LoRa, Sigfox, etc.). Ultra-high gain 40dB: only 5dBm (3mW) input is required to drive, reducing the requirements of the front-stage signal source. Wide voltage power supply: 20-28V DC (24V recommended), adaptable to different power supply environments. Industrial-grade design: 50 impedance matching, SMA female interface. Heat dissipation optimization: an external heat sink is required to long-term stable operation. Technical parameters: Frequency range: 833MHz-903MHz (center frequency 868MHz) Output power: 13W (41dBm@24V, input 5dBm) 15W (42dBm@28V, input 5dBm) 20W (43dBm@28V, input 7dBm) Gain: 40dB (typical value) Working voltage: 20-28V DC (24V recommended) Working current: about 1.7A (depending on voltage adjustment) Interface type: SMA female (external screw inner hole) Application areas: Internet of Things (IoT) devices: LoRa, Sigfox and other 868MHz frequency band communication systems. Wireless data transmission module: remote monitoring, smart instrumentation, industrial automation. test equipment: signal amplification, laboratory and production line testing. Security and drones: long-distance image transmission, remote control link enhancement. Notes: An external heat sink is required to long-term high-power operation stability. (Heat sink not included) The input signal should not exceed the nominal value (5dBm@15W) to avoid damage to the device. 50 impedance matching to avoid reflected power resulting in reduced efficiency.
