GENERAL DESCRIPTION

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.

APPLICATIONS

► 45 MHz to 1800 MHz CATV infrastructure amplifier systems

► 5 MHz to 700 MHz upstream

► Remote physical layer (PHY)

► DOCSIS® 3.1 and DOCSIS 4.0 compliant

ADCA5191ACPZ属于RF/IF，射频/中频和 RFID > 射频放大器。亚德诺半导体技术有限公司制造生产的ADCA5191ACPZ射频放大器在射频应用中，射频放大器产品可用于信号增益和缓冲。这些产品与通用运算放大器的不同之处在于，它们通常适用于更高的频率，更倾向于提供不可调节的固定增益，并且输入或输出阻抗值符合常用传输线特性阻抗。
