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 ACA2401 is cascaded between two appropriate transmission line baluns.

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.
