ACA2402 750/870 MHz CATV Push-Pull Line Amplifier PRELIMINARY DATA SHEET - Rev 1.2 FEATURES • 22 dB Gain • Very Low Distortion • Excellent 75 Ω Input and Output Match • 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 • Meets Cenelec Standards APPLICATIONS • S7 Package 16 Pin Wide Body SOIC with Heat Slug CATV Line Amplifiers, System Amplifiers, Distribution Nodes PRODUCT DESCRIPTION The ACA2402 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 ACA2402 is cascaded between two appropriate transmission line baluns. 1A 2A 1B 2B RF Input RF Output ACA2402 Figure 1: Hybrid Application Diagram 11/2002 ACA2402 1 GND GND 16 2 2A IN 1A OUT 15 3 GND Bias 1A 14 4 1A IN 2A OUT 13 5 1B IN 2B OUT 12 6 I SET Bias 1B 11 7 2B IN 1B OUT 10 8 GND GND 9 Figure 2: Pin Out Table 1: Pin Description 2 PIN NAME 1 GND 2 DESCRIPTION PIN NAME Ground 16 GND Ground 2AIN Amplifier 2A Input 15 1AOUT Amplifier 1A Output 3 GND Ground 14 B i as 1A 4 1AIN Amplifier 1A Input 13 2AOUT Amplifier 2A Output and Supply 5 1BIN Amplifier 1B Input 12 2BOUT Amplifier 2B Output and Supply 6 ISET Current Adjust 11 B i as 1B 7 2BIN Amplifier 2B Input 10 1BOUT Amplifier 1B Output 8 GND Ground 9 GND Ground PRELIMINARY DATA SHEET - Rev 1.2 11/2002 DESCRIPTION Bias for 1A Amplifier Bias for 1B Amplifier ACA2402 ELECTRICAL CHARACTERISTICS Table 2: Absolute Mimimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply (pins 12, 13) 0 +28 VD C RF Power at Inputs (pins 4, 5) - +75 dBmV -65 +150 °C Soldering Temperature - +260 °C Soldering Time - 5.0 S ec Storage Temperature Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: 1. Pins 2, 4, 5 and 7 should be AC-coupled. No external DC bias should be applied. 2. Pin 6 should be AC-grounded and/or pulled to ground through a resistor for current control. No external DC bias should be applied. 3. Pins 11 and 14 are bias feeds for input amplifiers 1A and 1B. No external DC bias should be applied. 4. Pins 10 and 15 receive DC bias directly from pins 11 and 14. No other external bias should be applied.
