Abstract
A dual band transmitter for transmitting a data signal in a first frequency or second frequency band. An antenna receives and sends data in one of the first and second frequency bands. An impedance matching network is connected in series with the antenna, and to a first node, and matches the impedance of the antenna to a predetermined value. The impedance matching network includes first and second antenna matching networks. The first antenna matching network is connected in series with the second matching network. In the first frequency band, the first antenna matching network matches the impedance of the antenna to the predetermined value, and in the second frequency band the second antenna matching network matches the impedance of the antenna to the predetermined value without affecting the first antenna matching network's matching in the first frequency band.
