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 RF Input 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 ACA2401 is cascaded between two appropriate transmission line baluns. 1A 2A 1B 2B ACA2401 Figure 1: Hybrid Application Diagram 08/2001 RF Output ACA2401 1 GND GND 16 2 2AIN 1AOUT 15 3 GND Bias 1A 14 4 1AIN 2AOUT 13 5 1BIN 2BOUT 12 6 ISET Bias 1B 11 7 2BIN 1BOUT 10 8 GND GND 9 Figure 2: Pin Out Table 1: Pin Description 2 PIN N AME 1 GND 2 D ESC R IPTION PIN N AME Ground 9 GND Ground 2AIN Ampli fi er 2A Input 10 1BOUT Ampli fi er 1B Output 3 GND Ground 11 B i as 1B 4 1AIN Ampli fi er 1A Input 12 2BOUT Ampli fi er 2B Output and Supply 5 1BIN Ampli fi er 1B Input 13 2AOUT Ampli fi er 2A Output and Supply 6 ISET C urrent Adjust 14 B i as 1A 7 2BIN Ampli fi er 2B Input 15 1AOUT Ampli fi er 1A Output 8 GND Ground 16 GND Ground Data Sheet - Rev 2.0 08/2001 D ESC R IPTION Bi as for 1B Ampli fi er Bi as for 1A Ampli fi er ACA2401 ELECTRICAL CHARACTERISTICS Table 2: Absolute Mimimum and Maximum Ratings PAR AMETER MIN MAX U N IT Supply (pi ns 12, 13) 0 +28 VD C RF Power at Inputs (pi ns 4, 5) - +75 dBmV -65 +150 °C Solderi ng Temperature - +260 °C Solderi ng Ti me - 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.
