Abstract
An impedance matching network for a radio frequency (RF) transmission system can include first port for coupling to a first transistor differential pair. The network can further include a second port for coupling to a second transistor differential pair. The network can further include a matching network connected to the first port and the second port, the matching network comprised of a pair of coupled lines. Other aspects are described.
