Offered in a convenient surface mount package,theMMICconsistsoftwopairsofparallel amplifiers that are optimized for exceptionally low distortion. A hybrid equivalent that provides flat gainresponseandexcellentinputandoutputreturn loss over the 40 to 1000 MHz CATV downstream band is formed when one ACA2420 is cascaded betweentwoappropriatetransmissionlinebaluns.

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. Pins11and14arebiasfeedsforinputamplifiers1Aand1B.NoexternalDC bias should be applied. 4. Pins 10 and 15 receive DC bias directly from pins 11 and 14.
