DISCONTINUED Professional Rack-Mounted Power-Doubling Distribution AmplifiersLimited Availabililty The R.L. Drake model DAR8642A, DAR8633A and DAR7533A broadband distribution amplifiers are designed for indoor headend use in both residential and commercial buildings where RF signal distribution in the frequency range of 54 to 750 or 860 MHz is required. Each model incorporates a push-pull hybrid input preamp and a power doubled hybrid output amplifier to provide a very low distortion signal for launch amplifier applications in the output of an SMATV or CATV headend. The Gain and Slope controls both have a range of 10 dB minimum and operate between the preamp hybrid and the output hybrid to maintain a low noise figure over a wide range of gain and slope settings. All models have a provision for optional fixed input attenuators and equalizers. Double-sided, plated through hole, glass epoxy printed circuit boards, and SMT construction are used for low losses and maximum reliability. Input and output test connectors are provided for convenient monitoring of the signal path. The amplifier circuitry is designed for maximum stability, low distortion, low noise figure, and is protected in a rugged aluminum housing. The units operate from a nominal 120 VAC, 60 Hz AC Input Product Documents & Videos Spec Sheet Click to Download User Manual Click to Download
