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

Technical specifications:
– Shipping Weight: 0.8Kg
– 180-225MHz 63V @ 32A
– Output power: 1400W peak (pulsed), 300-400W (DAB+), 250W (DVB/T)
– Efficiency >45% Analog TV, 30% DAB+
– Input/Output 50 ohms
– Pout: ~1400W with ~ 8W input
– Temperature compensated bias designed by NXP.
– Size (LxWxH): 130×52.8x30mm

– 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.
– 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.

Quantity discount is available and shipping becomes a lot cheaper per unit as quantity goes up. For additional info and prices please ask for a quote here.

NOTE: The actual pallet differs slightly than the one shown on the photo (updated photo coming soon).
