1400Wpp VHF/DAB+/DVB-T band III pallet amplifier using ART2K0 with planar input/output transformer, super low profile
Designed for DAB+ digital radio, analog band III VHF TV and other band III radio transmitters this amplifier uses a single ART2Ko push-pull transistor to produce ~1500 watts peak @65V DC!
Recommended voltage supply: 55-63V DC
Operating Temperature range: 0 to +70 °C ( at Device Flange )
Storage Temperature range: -30 to +90 °C
Load Mismatch: 20:1 (all phase angle)
Ensure sufficient airflow across the top of the pallet, the PCB and capacitors will get hot at max power

You can find special 65V power supply for this amplifier here!
– Ensure shielding between final stage and audio stage with exciter. Install a good feed-through capacitor on the supply +65V wiring feeding the power output stage. This will keep and RF from the power line.
– 放大器效率是電源電壓的函數，為了獲得最大效率，請根據所需輸出功率減少電源。通常，當放大器工作在大約 2-3 dB 增益壓縮時，可以獲得效率和諧波發射之間的最佳折衷。
– RF pallets are sensitive devices, if you do not have sufficient experience please consider a fully finished product instead. They can be burned by applying too much drive power, too high supply voltage, not using proper heatsink, using filter with insufficient specifications, connecting mismatched loads or no load at all and also by soldering coax with too long leads. For this reason there is no warranty for any pallet. We do assure you that every pallet is tested and is 100% operational as it leaves our workshop.
