Overview
19-3025; Rev 1; 6/06 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.
The MAX3558 also includes a power detector that can be used to close the loop on any of the AGCs to prevent overload conditions.
The LNA’s attack point is adjustable with an external resistor.
The MAX3558 is available in a very small 28-pin QFN package with exposed paddle (EP).
