Product Details

The ADCA5191 is a medium power gain block amplifier that provides excellent linearity across a flexible bias range allowing power efficient design implementation for various applications.

The device provides 25.8 dB of flat gain up to 1800 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 700 MHz as the output stage. It is conveniently packaged in an industry-standard, 5 mm × 5 mm, 32-lead, lead frame chip-scale package (LFCSP) with an exposed pad on the bottom of the package for improved thermal performance.
