Amplifier Technology has developed a new range of communications amplifiers for the broadcast market – the 8800 and 8801 COFDM linear amplifiers, which are nominally rated at 1 watt and 5 watts respectively.
Both amplifiers operate at between 2.0GHz and 2.8GHz for video at QPSK, 16QAM and 64QAM modulation schemes, which makes them ideally suited for outside broadcast applications, for example for use with wireless cameras.
The 1 watt amplifier, model 8800, measures 110mm x 60mm, while the 5 watt amplifier, model 8801, is slightly larger, at 155 x 115 mm. Both are easily portable via a 12V supply. Test results show good linearity across the band.
