Features

Description

Typical Performance

Absolute Maximum Ratings

The ASL31C, a wideband linear amplifier MMIC,

has a high linearity and low noise over a wide range

of frequency 5 MHz to 1.2 GHz, being suitable for

use in the fiber receiver, distribution amplifiers and

drop amplifiers of CATV systems, and in the mobile

wireless repeaters. The amplifier is available in a

SOT89 package and passes through the stringent

DC, RF, and reliability tests.
