Opis
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
Raspon radne temperature: 0 do +70 °C (na prirubnici uređaja)
Raspon temperature skladištenja: -30 do +90 °C
Neusklađenost opterećenja: 20:1 (svi fazni kut)
Osigurajte dovoljan protok zraka preko vrha palete, PCB i kondenzatori će se zagrijati pri maksimalnoj snazi

VAŽNO:
– Ensure shielding between final stage and audio stage with exciter. Install a good feed-through kondenzator on the supply +50V(or more) wiring feeding the power output stage. This will keep and RF from the power line.
– Excessive drive level can damage this amplifier; design of equipment where the amplifier will be mounted must foresee an appropriate protection circuits.
– Amplifier efficiency is function of supply voltage, in order to obtain max efficiency please reduce supply in function of desired output power. Generally best compromise between efficiency and harmonic emission, is obtained when the amplifier work at about 2-3 dB of gain compression.
– 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.
