ACA2420

ADVANCED PRODUCT INFORMATION - Rev 0.1 High Output Power Doubler Line Amplifier 24V, 1000 MHz, 21.5dB Gain ACA2420 FEATURES • 21.5 dB Gain • 75 V input and output match • Characterized at +58dBmV output power • Superior gain flatness (+ 0.2dB) • Very Low Distortion • Stable with High VSWR Load Conditions • Monolithic GaAs Design for Consistent Performance Part-to-Part • Surface Mount Package Compatible with Automatic Assembly • RoHS Compliant Package APPLICATIONS • CATV Line Amplifiers, Deep Fiber Nodes S7 Package 16 Pin Wide Body SOIC with Heat Slug PRODUCT DESCRIPTION The ACA2420 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. A hybrid equivalent that provides flat gain response and excellent input and output return loss over the 40 to 1000 MHz CATV downstream band is formed when one ACA2420 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. 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.
