Amplifier design specialist Amplifier Technology Ltd 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 2.0 GHz and 2.8 GHz 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, measures110mm 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.
Amplifier Technology Ltd, based just outside Bristol in the UK, designs and manufactures RF power amplifiers. The company is an approved supplier for defence and industrial contracts.
Amplifier Technology also offers bespoke RF amplifier design services - there are technical resources for systems designers at www.amplifiertechnology.com.
