Product Attributes

Introduction

• The MAX2130 is a broadband, high-gain, low-distortion low-noise amplifier (LNA) with two outputs intended for operation over the 44MHz to 878MHz frequency range.
• The device operates from a +5V supply and features externally adjustable bias control circuitry that allows minimum linearity requirements to be met while reducing current consumption.
• The IN port is a broadband 75Ω input that provides a guaranteed minimum input return loss of 7.4dB (allowing for 2:1 VSWR at output) across the 44MHz to 878MHz frequency range. AC-couple the IN port with a 0.1µF DC-blocking capacitor.
• The OUT1 port is a broadband, 75Ω, open-collector output for the LNA. It requires a pullup inductor to VCC for proper biasing, as well as a 0.1µF DC-blocking capacitor.
• The OUT2 port is a broadband, 75Ω output for the loopout amplifier.

Features

• The MAX2130 broadband, low-distortion, low-noise, two-output amplifier performs preamp, loop-out, and buffer functions in TV tuner applications.
• The device integrates functions typically achieved with discrete components into the space-saving 8-pin µMAX-EP package.
• The MAX2130 provides a gain of +15dB with a noise figure less than 3.2dB over the 44MHz to 878MHz frequency range.
• The MAX2130 features an externally adjustable bias control, set with a single resistor, that allows the user to meet minimum linearity requirements while reducing current consumption.
• The device operates from a +5V single supply and only requires 93mA of supply current when nominally biased.

Applications

• DVB-T Digital Broadcast Receivers
• Digital/Terrestrial TV Tuners
• Set-Top Boxes
• Cable Modems
• Analog TV Tuners
