A broad-band linear amplifier circuit includes a driver amplifier to produce a first amplified radio frequency (RF) signal in a first single RF band in response to a first input RF signal and to produce a second amplified RF signal in a second single RF band in response to a second input RF signal. The first single RF band and the second single RF band reside in a broad band that has a bandwidth more than two times a bandwidth of the first single RF band or the second single RF band. A sensing circuit can sense a power, a gain, or a phase of the first output RF signal and the second output RF signal, and to produce a sensing signal. A gain control circuit controls gain variation of the driver amplifier in response to the sensing signal.

A radio frequency (RF) amplifier circuit includes a first impedance matching circuit configured to receive an input RF signal, a control circuit configured to produce a band control signal according to the frequency of the input RF signal, an RF amplifier having its input connected to the first impedance matching circuit. The RF amplifier can produce an amplified RF signal in response to the input RF signal. A second impedance matching circuit can receive the amplified RF signal from the RF amplifier. At least one of the first impedance matching circuit and the second impedance matching circuit has an impedance that is adjustable by the band control signal. A multi-band filter can switch the amplified RF signal from the second impedance matching circuit to one of selectable narrow-band filters in response to the band control signal.

An apparatus for interfacing communication and computing devices to a vehicle's entertainment system, data system, and/or vehicle's diagnostics system to minimize driver distraction and to integrate the latest computing technologies for entertainment, information, and applications to the vehicle. Such an interface may be provided by hardware, firmware or software provided in the vehicle, computing and communication devices or both. The interface not only provides a link but also translates the data, commands and responses of one to data, commands and responses understandable by the other.
