ACA2408

ACA2408 870 MHz, 34 dB Gain CATV Push-Pull Line Amplifier PRELIMINARY DATA SHEET - Rev 1.0 FEATURES 34dB Gain Very Low Distortion Stable with High VSWR Load Conditions Monolithic Design for Consistent Performance Part-to-Part Low DC Power Consumption Surface Mount Package Compatible with Automatic Assembly Low Cost Alternative to Hybrids APPLICATIONS www.DataSheet4U.com Line Extenders, Apartment House Amplifiers, System Amplifiers, Distribution Nodes S7 Package 16 Pin Wide Body SOIC with Heat Slug PRODUCT DESCRIPTION The ACA2408 is a highly linear, monolithic GaAs RF amplifier that has been developed to replace, in new designs, standard CATV hybrid amplifiers. Offered in a convenient surface mount package, the MMIC consists of two pairs of parallel amplifiers that are optimized for exceptionally low distortion and noise figure. A hybrid equivalent that provides flat gain response and excellent input and output return loss over the 40 to 870 MHz CATV downstream band is formed when one ACA2408 is cascaded between two appropriate transmission line baluns. 1A RF Input 1:1 2A 1:1 RF Output 1B 2B ACA2408 Figure 1: Hybrid Application Diagram 07/2003 ACA2408 1 2 3 4 5 6 7 8 www.DataSheet4U.com GND 2A IN GND 1A IN 1B IN I SET 2B IN GND Figure 2: Pin Out GND 1A OUT Bias 1A 2A OUT 2B OUT Bias 1B 1B OUT GND 16 15 14 13 12 11 10 9 Table 1: Pin Description PIN 1 2 3 4 5 6 7 8 NAME GND 2AIN GND 1AIN 1BIN ISET 2BIN GND DESCRIPTION Ground Amplifier 2A Input G...
