About this product
This 100–400MHz 50W broadband power amplifier supplies stable 47dBm (50W) output power and 40dB gain across the full frequency range.Built in a tough aluminum enclosure with SMA connectors and integrated power control, it delivers consistent wideband amplification for critical communication systems.
Features
Wide-range 100–400MHz Broadband RF Module – Covers full frequency band for multi-band radio signal boosting.
Impressive 40dB High Gain – Efficiently amplifies faint incoming radio signals to extend transmission distance.
Uniform ±0.5dB Gain Flatness – Keeps steady signal strength across the entire working frequency range.
Excellent 45% Power Efficiency – Cuts power consumption and minimizes excess heat during operation.

Attentions
1）The input power shall NOT exceed 10dBm to avoid damage.
2）Connect antenna and secure all cables before power-on,do not power on without antenna load.
3）Power supply recommended: 10W:24V@2A; 20W:24V@3A; 30W:28V@4A; 40W:28V@5A; 50W:28V@5A; 60W:28V@6A
4）Maintain good ventilation for heat disspation,a heat sink or cooling fan is recommended.
5）Never swap RFin /ANT ports,reversed wiring will damage the amplifier.
