Abstract
In one form, a radio frequency (RF) transmitter includes an RF signal source, a balanced/unbalanced transformer (balun), and first and second amplification circuits. The balun has a primary side adapted to be coupled to an antenna, and a secondary side. The first amplification circuit has an input coupled to the RF signal source, and an output coupled to the primary side of the balun. The second amplification circuit has an input coupled to the RF signal source, and an output coupled to the secondary side of the balun. The second amplification circuit has a higher output power than the first amplification circuit.
