Abstract

See full text

An RF amplifier suitable for use in an RF transceiver has a circuit including a first transistor pair with the collector of each coupled to one of the two differential output nodes and a common base. A pair of Ft doublers is provided with the emitter of each Ft doubler coupled to one of the transistors in the first transistor pair. Each Ft doubler has a common emitter and a base coupled to one of the differential input nodes. As such, the first transistor pair and the Ft doubler pair are cascode-coupled to provide a wide bandwidth, high gain, and high input impedance RF amplifier.
