PCS Electronics 3000W Pallet Amplifier
The new PCS Electronics 3000W Pallet Amplifier using the Ampleon ART2K0FE LDMOS makes it possible to create highly rugged 3000W (>3000W pulsed) pallets for high VSWR industrial and broadcast (analogue and digital) applications. You will likely have to parallel two PSU units to supply the power to this pallet. Make sure to select a power supply that supports paralleling.
Specifications
- Device: 2xAmpleon ART2K0FE
- Efficiency: >80% efficiency @ 88-108Mhz CW
- Power Output: Up to 3200W at 62V, even more at 65V per device (two onboard)
- Recommended Voltage Supply: 62-65V DC
- Supply Current: >60A
- Operating Temperature Range: 0 to +70°C (at Device Flange)
- Storage Temperature Range: -30 to +90°C
- Load Mismatch: 65:1 (all phase angle)
Note: Ensure sufficient strong airflow across the top of the pallet, as the PCB can get very hot at max power! This pallet requires a good heatsink.
IMPORTANT
- Ensure shielding between the final stage and audio stage with the exciter. Install a good feed-through capacitor on the supply +60V wiring feeding the power output stage. This will keep RF from the power line.
- Excessive drive level can damage this amplifier; the design of equipment where the amplifier will be mounted must foresee appropriate protection circuits.
- Amplifier efficiency is a function of supply voltage. To obtain max efficiency, reduce supply in function of desired output power. Generally, the best compromise between efficiency and harmonic emission is achieved when the amplifier operates at about 2-3 dB of gain compression.
- RF pallets are sensitive devices. If you lack sufficient experience, please consider a fully finished product instead. RF pallets can be damaged by:
- Applying too much drive power
- Using too high supply voltage
- Not using a proper heatsink
- Using a filter with insufficient specifications
- Connecting mismatched loads or no load at all
- Soldering coax with too long leads
- There is no warranty for any pallet, but we assure that every pallet is tested and is 100% operational when it leaves our workshop.
