MAX2067 Overview
The MAX2067 high-linearity analog variable-gain amplifier (VGA) is a monolithic SiGe BiCMOS attenuator and amplifier designed to interface with 50Ω systems operating in the 50MHz to 1000MHz frequency range (see the Typical Application Circuit). The analog attenuator is controlled using an external voltage or through the SPI™-patible interface using an on-chip 8-bit DAC. Because each stage has its own RF input and RF output, this ponent can be configured to either optimize NF (amplifier configured first), or OIP3 (amplifier last). The device’s performance
