Low-Noise, High-Linearity
Broadband Amplifier
General Description
The MAX3524 broadband amplifier is designed specifi-
cally for cable television receiver and cable modem
applications. The MAX3524 is a single-ended input, dif-
ferential-output low-noise amplifier (LNA) that offers
15dB of gain. It operates from a +4.75V to +5.25V sin-
gle supply from 44MHz to 880MHz. The MAX3524
includes an operational amplifier that is used to control
an off-chip PIN attenuator circuit at the input of the LNA.
The attenuator is typically used to regulate the input
signal to a value that maintains high linearity for large
signals. The MAX3524 is available in a 10-pin μMAX ?
package with an exposed paddle (EP) and operates in
the extended temperature range (-40°C to +85°C).
