PRODUCT DESCRIPTION
The ACA2408 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 excellent input and output return loss
over the 40 to 870 MHz CATV downstream
band is formed when one ACA2408 is cascaded
between two appropriate transmission line baluns.
FEATURES
