KIT ATION EVALU E L B AVAILA
Quad-Output LNA with AGC for Cable TV Applications
General Description Features
♦ Quad Outputs with Independent AGCs and Shutdown ♦ 50MHz to 878MHz Broadband Operation ♦ Integrated Power Detector ♦ High Linearity: 15.6dBm IIP3
MAX3558
The MAX3558 broadband quad-output low-noise amplifier (LNA) is designed for digital set tops and digital terrestrial applications. The LNA covers a 50MHz to 878MHz input frequency range, while integrating a separate automatic gain-control (AGC) function with over 30dB of control range for each of four balanced outputs. Each output has its own shutdown control to reduce power consumption when not used.
