Abstract
An impedance matching network between a transmitter and an antenna. The impedance matching network comprises of a watt meter coupled to the transmitter for measuring a standing wave ratio ('SWR'). A first unbalanced to unbalanced transformer ('first unun') with an impedance ratio of N:1 is selectively coupled in series with the watt meter. A microprocessor is coupled to the watt meter for determining iteratively whether the first unun lowers the standing wave ratio (“SWR”) in response to switching the first unun in and out of a series connection with the antenna.
