Abstract:
A method for operating a multi-mode transmitter, the method comprising the steps of:receiving a first, a second, and a third in phase component, and a first, a second, and a third quadrature component;determining a mode of operation; andbased on the mode of operation, summing the first and the third in phase components to produce a first summed component, and subtracting the third quadrature component from the first quadrature component to produce a second summed component;based on the mode of operation, mixing the first summed component with a cosine function to produce a first mixed component and mixing the second summed component with a sine function to produce a second mixed component;based on the mode of operation, summing the first and the second mixed components with the third in phase component.
