Designed for high-power FM broadcasting applications, this FM Pallet Amplifier stands out with wideband performance and reliable operation. It delivers efficient power amplification across the 88–108 MHz range and ensures long-term stable use with its integrated heatsink and cooling system. 

Specifications:

• Gain: 25 dB
• Input Power: 44 dBm
• Supply Voltage: 52 V
• Bandwidth: 88–108 MHz
• Transistors: 4 × MRF1K50H
• Filter: Integrated directional coupler (with DC outputs for forward power and reflected power measurements)
• Heatsink: Included
• Cooling Fans: 3 × 24 VDC, 92×92×38 mm fans mounted on the heatsink at the RF output connector side. In your enclosure design, airflow must be directed from the front towards the RF output connector side.

Applications:

• FM broadcast transmitters
• High-power RF amplification systems
• Research facilities: particle accelerators, plasmatrons, cyclotrons

Advantages:

This amplifier provides high efficiency and low distortion, ensuring reliable power amplification in FM broadcast systems. Its robust design and integrated cooling solution make it suitable for long-lasting, uninterrupted operation.

Important Notice:

Pallet amplifiers are sensitive devices. If you lack sufficient experience, consider a fully assembled product instead. Damage may occur due to:

• Excessive drive power
• Over-voltage supply
• Inadequate heatsinking
• Insufficient filter specifications
• Operating without a proper load
• Improper handling of coaxial connections (e.g., excessively long stripped cable ends)

For this reason, no warranty is provided for pallet amplifiers. However, each unit is thoroughly tested and guaranteed to be 100% operational at the time of delivery.
