The LTC6433-15 is a highly linear, fixed-gain amplifier The LTC6433-15 starts with a classic RF gain-block topol- that is configured to operate single ended. Its core signal ogy but adds additional enhancements to achieve dramati- path consists of a single amplifier stage minimizing cally improved linearity. Shunt and series feedback are stability issues. The input is a Darlington pair for high added to lower the input/output impedance and match them input impedance and high current gain. Additional circuit simultaneously to the 50Ω source and load. Meanwhile, enhancements increase the output impedance and minimize an internal bias controller optimizes the internal operating the effects of internal Miller capacitance. point for peak linearity over environmental changes. This circuit architecture provides low noise, excellent RF power handling capability and wide bandwidth—characteristics that are desirable for IF signal chain applications. 643315f 10 For more information www.linear.com/LTC6433-15 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information DC Electrical Characteristics AC Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Test Circuit A Operation Applications Information S Parameters Package Description Related Parts Features Applications Typical Application Description Absolute Maximum Ratings Order Information DC Electrical Characteristics Pin Configuration AC Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Test Circuit A Operation S Parameters Package Description Typical Application Related Parts
