Class A Amplifiers Drive CATV Systems

Feb. 9, 2011

A line of SOT115J-packaged hybrid cable-television (CATV) amplifiers developed by ANADIGICs is now available from Richardson Electronics. The amplifiers provide high gain from 40 to 870 MHz, with models ACA3742, ACA3747, and ACA3753 providing 21, 25, and 28 dB gain, respectively. The amplifiers are designed around a balanced Class A GaAs amplifier with low noise figure and low distortion. These amplifiers, previously only available in surface-mount-technology (SMT) packaging, are ideal for use in distribution amplifiers, fiber nodes, and line extenders in CATV infrastructure systems. The gain flatness is as good as 0.2 dB across the full frequency band.
