129CH Rack Mount Distribution Amplifier, 42dB Forward Gain
Series: DAR
Model: DAR8642
Provision for optional fixed input attenuators and equalizers
Double-sided, plated through hole, glass epoxy printed circuit boards and SMT construction for low losses and maximum reliability
Includes built-in diplexer filter to allow return path energy for presenting at output port of DAR to be separated from DAR output and passed to return path output port
Input and output test connectors are provided for convenient monitoring of signal path
Amplifier circuitry is designed for maximum stability, low distortion and low noise figure
The broadband distribution amplifier designed for indoor head-end use in both residential and commercial buildings where RF signal distribution in frequency range of 54 to 860MHz is required. Each model, except DAR8618, incorporates a push-pull hybrid input preamp and a power doubled hybrid output amplifier to provide a very low distortion signal for launch amp applications in the output of an SMATV or CATV head-end. The gain and slope controls both have a range of 10dB minimum and operate between preamp hybrid and output hybrid to maintain a low noise figure over a wide range of gain and slope settings. Only DAR8618 has a power doubled output hybrid with no input preamp and no adjustable gain and slope controls. All models have a provision for optional fixed input attenuators and equalizers. Double-sided, plated through hole, glass epoxy, printed circuit boards and SMT are used for low losses and maximum reliability.
