Radio frequency (RF) power amplifiers are commonly used in wireless communication devices (such as cellular phones, radios, and wireless modem) to amplify and transmit radio frequency (RF) signals. Radio frequency transmission of an electrical signal requires corresponding power amplification for the intended transmission range. RF signals typically have a broad frequency spectrum from several megahertz (MHZ) to tens of gigahertz (GHZ), and higher. A power amplifier amplifies an radio frequency signal at the output of a transmitter prior to transmission in a small-size communication device. A typical radio transmitter uses a radio frequency (RF) power amplifier to amplify outbound signals for transmission by an antenna. RF power amplifiers are generally designed to provide maximum efficiency at the maximal output power. Within the amplifier assemblies are typically plural printed circuit boards on which components that process the RF signals are mounted. Typically, a RF power amplifier consists of an integrated circuit chip having the transistors and other circuitry associated with the amplifier and a number of off-chip components that filter the signal or provide impedance matching at a particular operating frequency. RF signals are transmitted between the various processing components.
