The R.L. Drake model DA7533, DA7543, DA8632, DA8642, DA100032, and DA100042 broadband distribution amplifiers are designed for indoor use in both residential and commercial buildings where RF signal distribution in the frequency range of 49 to 750 MHz, 49 to 860 MHz, or 49 to 1000MHz 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 a cable television ”drop”, the output of an SMATV headend, or a small 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.
