S7 Package 16 Pin Wide Body SOIC with Heat Slug APPLICATIONS • CATV Line Amplifiers, System Amplifiers, Distribution Nodes PRODUCT DESCRIPTION The ACA2407 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 RF Input excellent input and output return loss over the 40 to 1000 MHz CATV downstream band is formed when one ACA2407 is cascaded between two appropriate transmission line baluns. 1A 2A 1B 2B ACA2407 Figure 1: Hybrid Application Diagram 12/2008 RF Output ACA2407 Figure 2: Pin Out Table 1: Pin Description 2 PIN NAME DESCRIPTION PIN NAME DESCRIPTION 1 GND Ground 9 GND Ground 2 2AIN Amplifier 2A Input 10 1BOUT Amplifier 1B Output 3 GND Ground 11 Bias 1B Bias for 1B Amplifier 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 1SET Current Adjust 14 Bias 1A Bias for 1A Amplifier 7 2BIN Amplifier 2B Input 15 1AOUT Amplifier 1A Output 8 GND Ground 16 GND Ground Data Sheet - Rev 2.3 12/2008 ACA2407 ELECTRICAL CHARACTERISTICS Table 2: Absolute Mimimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply (pins 12, 13) 0 +28 VDC Current Adjust (pin 6) 0 +4 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. Pins 11 and 14 are bias feeds for input amplifiers 1A and 1B. No external DC bias should be applied. 3. Pins 10 and 15 receive DC bias directly from pins 11 and 14. No other external bias should be applied.
