High Performance 50W 2000-6000MHz RF Power Amplifier Module with MCU Controller

50W RF Power Amplifier Module delivers 47dBm saturated output across 2000-6000MHz with ±2dB flatness, engineered for lab & industrial systems. Integrated MCU enables smart RS485 control: real-time status monitoring, over-temperature protection (85℃ cutoff), VSWR alarm (>5:1 auto-shutdown), and overcurrent/undervoltage protection. Military-grade reliability operates at -40~+60℃ with ≥35% efficiency under +28V DC. Compact 140×70×20mm design features LED indicators for power/operation/fault status, ideal for radar, RF testing, and communication systems integration.

Product Detail

Engineered for precision RF applications, 50W RF Power Amplifier Module delivers robust 47dBm saturated power across 2000-6000MHz with exceptional ±2dB flatness. This industry-grade PA module features <4dB gain variation and ≤1.8 VSWR at both ports, guaranteeing signal integrity for broadband communication, radar, and test systems.

Key Technologies:

Advanced MCU Control via RS485 interface (6-pin connector included): Enables remote amplifier status monitoring (temperature, VSWR, faults), ON/OFF switching (default ON), and multi-layer protection – thermal shutdown (>85℃ cutoff/<65℃ recovery), VSWR protection (>5:1 auto-shutdown), overcurrent (>15A cutoff), and reverse polarity protection;
High Efficiency: Maintains ≥35% efficiency throughout 2000-6000MHz band at 5.5A typical current under +28V DC;
Military-Grade Durability: Operates at -40~+60℃ with >20dBc harmonic suppression and >60dBc non-harmonic spurious rejection;
Compact Integration: SMA-KFD RF ports, feed-through capacitor power interface, and 140×70×20mm footprint (133.5×63.5mm mounting pattern).

And Internally Pulled-Low (0V), indicating the amplifier should be ON by default; 3) Over-temperature Alarm: the recommended threshold is +85℃. When the detection temperature exceeds +85℃, an alarm is triggered and the amplifier is switched off. When it reaches +65℃, the amplifier is switched on; 4) Standing Wave Alarm: When the standing wave detection exceeds 5:1, the amplifier automatically switchs off; 5) Overvoltage and Undervoltage Alarm: When voltage exceeds 32V &below 24V, the amplifier automatically switchs off; 6) Overcurrent Alarm: When current exceeds 15A, the amplifier automatically switchs off; 7) Reverse Polarity Protection.
