Description

1000W 470-705MHz UHF TV Pallet Amplifier

This revolutionary design is based on two NXP BLF989 50V LDMOS transistors. The pallet is ideal for digital and analog TV broadcast applications. In digital the pallet can do 280-350 watts. In analog application this amplifier can run up to 1000 watts peak-sync analog TV power.

IMPORTANT:
– A good shielding between final stage and any driver/low power stage is required. Please foresee a good RF choke also on the supply wiring.
– Excessive drive level can damage this amplifier!
– A suitable protection system should switch off (or reduce) the input power in case of excessive reflected power (load matching ≥ -10 dB). Due to extreme ruggedness of this NXP mosfet, this power amplifier can manage up to 1000Wps of reflected power but only for a short time (t ≤ 1 sec). If the load matching is higher than -10 dB, a suitable protection must be used in order to prevent damage.
– RF pallets are sensitive devices, if you do not have sufficient experience please consider a finished product instead. They can be burned by applying too much drive power, too high supply voltage, not using proper heatsink, 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.
