The LTC6432-15 is an ultra-high dynamic range differentialgain block amplifier designed to drive high resolution,high speed ADCs. It offers a full GHz of data bandwidt h forcomplex spectrally efficient modulations schemes or wh ereresistance to blockers is critical. This unique device cansimultaneously 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.All A-Grade LTC6432-15 devices are tested and guaranteed for OIP3 at 150MHz. The LTC6432-15 is housed in a 4mm × 4mm, 24L, QFN package with an exposed pad for thermal management and low inductance.For a single-ended 50Ω IF Gain Block with similar performance, see the related LTC6433-15.ApplicationsDifferential 1GHz Bandwidth ADC DriverWideband Test Instrument AmplifierDifferential IF Amplifier50Ω/75Ω Balanced IF Amplifier
