Multifunctional RF limiting amplifier
Abstract
Multifunctional RF limiting amplifiers having various configurations and functions are disclosed. In a first configuration, the RF limiting amplifier includes an active load output circuit that allows one to adjust the output impedance based upon the anticipated connected load impedance. In a second configuration, the RF limiting amplifier includes a pair of emitter-followers to buffer the output of a first stage, allowing the RF limiting amplifier to drive one or more second stages. A third configuration includes a pair of RF limiting amplifiers with their outputs mixed to implement a down conversion function. The third configuration may be used to drive dual SAW resonators for detecting the presence of biological or chemical agents. The RF limiting amplifier may be implemented in either bipolar junction transistors or CMOS transistors.
