This design is based on the new NXP BLF878 42V LDMOS transistor. The pallet is ideal for digital and analog TV broadcast applications. In DVB-T digital the pallet can do 150 watts and in 8VSB the pallet can do 200 watts. In analog application this amplifier can run up to 550 watts peak-sync. The copper base is machined from Tellurium Copper alloy 145. This is a high grade copper and it gives the pallet base the best possible surface finish which promotes efficent thermal transfer to the mounting surface.
