The LTC6433-15 is a gain-block amplifier with excellent linearity at frequencies below 100kHz to beyond 1000MHz and with low associated output noise.
The unique combination of high linearity, low noise and low power dissipation makes this an ideal candidate for many signal-chain applications. The LTC6433-15 is easy to use, requiring a minimum of external components. It is internally input/output matched to 50Ω and it draws only 95mA from a single 5V supply.
The LTC6433-15 operates over a wide bandwidth. A single demonstration circuit offers flat gain from 100kHz to 1GHz.
While this device is not capable of DC coupled operation, users can define the low frequency cut-off by appropriate choice of external components.
On-chip bias and temperature compensation maintain performance over environmental changes.
The LTC6433-15 uses a high performance SiGe BiCMOS process for excellent repeatability compared with similar GaAs amplifiers. All A-grade LTC6433-15 devices are tested and guaranteed for OIP3 at 150MHz. The LTC6433-15 is housed in a 4mm × 4mm 24-lead QFN package with an exposed pad for thermal management and low inductance.

Tools & Simulations
Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
