LTC6431AIUF-15#PBF

LTC®6431-15 is a gain-block amplifier with excellent linearity at frequencies beyond 1000MHz and with low associated output noise. The unique combination of high linearity, low noise and low power dissipation make this an ideal candidate for many signal-chain applications. The LTC6431-15 is easy to use, requiring a minimum of external components. It is internally input/output matched to 50 ohm and it draws only 90mA from a single 5V supply. On-chip bias and temperature compensation maintain performance over environmental changes. The LTC6431-15 uses a high-performance SiGe BiCMOS process for excellent repeatability compared with similar GaAs amplifiers. Typical applications include single-ended IF amplifier, ADC driver and CATV.
