For additional info and prices please ask for a quote here. Quantity discount is available and shipping becomes a lot cheaper per unit as quantity goes up. We do assure you that every pallet is tested and is 100% operational as it leaves our workshop. For this reason there is no warranty for any pallet. They can be burned by applying too much drive power, too high supply voltage, not using proper heatsink, using filter with unsufficient specifications, connecting mismatched loads or no load at all and also by soldering coax with too long leads. – RF pallets are sensitive devices, if you do not have sufficient experience please consider a fully finished product instead. Generally best compromise between efficiency and harmonic emission, is obtained when the amplifier work at about 2-3 dB of gain compression. – Amplifier efficiency is function of supply voltage, in order to obtain max efficiency please reduce supply in function of desired output power. – Excessive drive level can damage this amplifier design of equipment where the amplifier will be mounted must foresee an appropriate protection circuits. This will keep and RF from the power line. Install a good feed-through capacitor on the supply +50V wiring feeding the power output stage. – Ensure shielding between final stage and audio stage with exciter. You can find special 65V power supply for this amplifier here! – Temperature compensated bias designed by NXP. Operating Temperature range: 0 to +70 ☌ ( at Device Flange )Įnsure sufficient airflow across the top of the pallet, the PCB and capacitors will get hot at max power 1400W VHF/DAB+/DVB-T wideband pallet amplifier using ART2K0 with planar input/output transformer, super low profileĭesigned for FM radio transmitters this amplifier uses a single ART2Ko push-pull transistor to produce >1500 watts peak DC!
