Why Are Application and Fractional Bandwidth Fundamental to Choosing an RF Amplifier?Depending on the specifics of a particular amplifier application, there can be many critical RF parameters, including gain, P1dB, IP3, IP2, NF and efficiency. One fundamental requirement that is often overlooked, at least initially, is the application bandwidth.
