  • Multi-Stage RF Amplifier Including MMICs and Discrete Transistor Amplifiers in a Single Package
    Publication number: 20090039966
    Abstract: A MMIC amplifier stage and a discrete transistor amplifier stage are housed in a single package. In one aspect, a multi-stage RF amplifier includes a package with an RF input lead and an RF output lead. The signal path from the RF input lead to the RF output lead includes one or more MMIC amplifier stages followed by one or more discrete transistor amplifier stages. Each MMIC amplifier stage includes a MMIC with at least one amplifier, and each discrete transistor amplifier stage includes at least one discrete transistor amplifier. All of the MMIC amplifier stages and discrete transistor amplifier stages are housed in the same package.
