More Information
Summary:The amplifier uses transistors such as (metal oxide semiconductor field effect transistors) MOSFET transistors in a current mirror configuration. The MOSFET transistors are easy to package as surface mount devices. The output power of the amplifier is controlled by controlling the bias current flowing through the amplifier stage. Additionally, the amplifier has low sensitivity to the variations of the bias current to the control signal threshold. These characteristics make the amplifier ideal for use in a radio transmitter, such as a radiotelephone.
