Abstract
A mixer for a transmitter includes a voltage converter to convert a baseband voltage to a baseband current. A mixer component mixes the baseband current with a local oscillator frequency. An output of the mixer component includes a radio frequency signal and a higher order radio frequency signal. A coupler sends the radio frequency signal and the higher order radio frequency signal to a differential output. A filter is integrated into the coupler to filter the higher order radio frequency signal before being output by the differential output.
