LTC6432AIUF-15#PBF

LTC®6432-15 is an ultra-high dynamic range differential gain block amplifier designed to drive high resolution, high speed ADCs. It offers a full GHz of data bandwidth for complex spectrally efficient modulations schemes or where resistance to blockers is critical. This unique device can simultaneously achieve low noise, incomparable linearity and flat gain over the 100KHz to 1GHz band. Unlike wideband GaAs PHEMTs, MESFETs and GaN FETs, this SiGe based amplifier exhibits low 1/f noise and can be used down to 100KHz. The LTC6432-15 is designed for ease of use requiring a minimum of support components. Impedance matching, temperature compensation and bias control are handled internally to ensure consistent performance over environmental changes. Application includes differential 1GHz bandwidth ADC driver, wideband test instrument amplifier, differential IF amplifier, 50 ohm/75ohm balanced IF amplifier.
