A radio frequency amplifier includes a first amplifier stage having a first transistor, and a second amplifier stage having a second transistor. The first transistor has a base input for receiving an input voltage, a collector output, and an emitter coupled to a common. The second transistor has a base input coupled to the first transistor collector output, a collector output, and an emitter coupled to the common by a resistance element. The second transistor emitter is DC coupled to the first transistor base. The DC coupling of the first transistor base to the second transistor emitter provides stable DC biasing of the first and second transistors based on base-emitter voltages of the first and second transistors. The radio frequency amplifier may be employed in a variety of receiver/amplifier applications, such as vehicular driver integrity check systems.
