MAX2611

DC-to-Microwave, Low-Noise Amplifier

Overview

Technical Documents

Ordering Info

Status

Active: In Production.

Description

The MAX2611 is a low-voltage, low-noise amplifier for use from DC to microwave frequencies. Operating from a single +5V supply, it has a 3dB bandwidth of 1100MHz. The MAX2611's low noise figure and high drive capability make it ideal for a variety of transmit, receive, and buffer applications.

In a typical application, the only external components needed are input and output blocking capacitors and a V_CC series resistor. To improve gain and output power, an RF choke can be added in series to the bias resistor.

The MAX2611 comes in a 4-pin SOT143 package, requiring minimal board space.
