Ultra wide band low noise amplifier and method

摘要: An ultra wide band (UWB) low noise amplifier (LNA) includes a common-gate (CG) amplifying element in cascode with common-source (CS) element, and load-tracking (LT) network to, at least part, track changing output impedance of the helping to provide substantially constant gain over an frequency interest. The LT may include parallel combination capacitive inductive resistive which be selected band. initial stage compensate for input matched antenna also one or more resistor-based stages after cascode.
