Latest Patents

Robert E Johnston holds a patent for an "Analog multiplexer and variable gain amplifier for intermediate frequency applications." This invention involves a diversity receiver circuit system that includes a primary channel and a diversity channel. In this system, analog input signals are converted to differential signals in both channels. The receiver circuit system features a multiplexer and a variable gain amplifier formed on a single RF integrated circuit chip. The multiplexer is strategically positioned before the amplifier, allowing for efficient signal processing. The differential signals in both channels are applied to an amplified path and a non-amplified path in the multiplexer. A control signal selects one of the various signals, which is then processed through multiple amplifier stages in the variable gain amplifier.
