S7 Package 16 Pin Wide Body SOIC with Heat Slug APPLICATIONS • CATV Line Amplifiers, System Amplifiers, Distribution Nodes PRODUCT DESCRIPTION The ACA2407E 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 RF Input 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 ACA2407E is cascaded between two appropriate transmission line baluns. 1A 2A 1B 2B ACA2407E Figure 1: Hybrid Application Diagram 12/2008 RF Output ACA2407E 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: Pinout Table 1: Pin Description 2 PIN NAME Ground 9 GND Ground 2AIN Amplifier 2A Input 10 1BOUT Amplifier 1B Output 3 GND Ground 11 Bias 1B 4 1AIN Amplifier 1A Input 12 2BOUT Amplifier 2B Output and Supply 5 1BIN Amplifier 1B Input 13 2AOUT Amplifier 2A Output and Supply 6 ISET Current Adjust 14 Bias 1A 7 2BIN Amplifier 2B Input 15 1AOUT Amplifier 1A Output 8 GND Ground 16 GND Ground PIN NAME 1 GND 2 DESCRIPTION Data Sheet - Rev 2.4 12/2008 DESCRIPTION Bias for 1B Amplifier Bias for 1A Amplifier ACA2407E ELECTRICAL CHARACTERISTICS Table 2: Absolute Mimimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply (pins 12, 13) 0 +28 VDC RF Power at Inputs (pins 4, 5) - +75 dBmV -65 +150 °C Soldering Temperature - +260 °C Soldering Time - 5.0 Sec 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. 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.
