GENERAL DESCRIPTION
The ADCA5192 is a low power, low noise gain block amplifier that
provides excellent linearity across a flexible bias range allowing
power efficient design implementation for various applications.
The device provides 17.0 dB of flat gain up to 1794 MHz, making
this ideal for Data Over Cable Service Interface Specification (DOCSIS
®) 4.0 downstream applications. The device is also well suited
for upstream applications to 684 MHz as an input or intermediate
stage. The device is conveniently packaged in an industry-standard,
20-lead, 4 mm × 4 mm lead frame chip-scale package (LFCSP)
with an exposed pad on the bottom of the package for improved
thermal performance.
FEATURES
► Highly flexible: bias at 5 V from 500 mW to 1.5 W for downstream
applications, or as low as 250 mW for upstream applications
► Excellent linearity: NPR (MER) > 50 dB over broad input power
range
► High gain: 17.0 dB at 1794 MHz
► Low noise figure (includes input balun and trace losses)
► 1.7 dB at 108 MHz
► 2.9 dB at 1794 MHz
► Excellent S11 return losses:
► −20 dB from 108 MHz to 1218 MHz
► −19 dB from 1218 MHz to 1794 MHz
► 20-lead, 4 mm × 4 mm LFCSP
APPLICATIONS
► 54 MHz to 1794 MHz CATV infrastructure amplifier systems
► 5 MHz to 684 MHz upstream
► Remote physical layer (PHY)
► DOCSIS 3.1 and DOCSIS 4.0 compliant
