Abstract:
The present disclosure relates to systems, devices and methods related to transmitters, and/or transceivers having a single, tunable oscillator in a dual conversion architecture. In various exemplary embodiments, this transmitter may include: a first mixer configured to receive a first oscillator signal from the single oscillator; a filter configured to band pass filter the converted signal and output a filtered signal; and a second mixer in communication with the filter, configured to receive the filtered signal. This dual conversion transmitter may be configured to receive a communication signal from an input to the transmitter and to output a converted signal based on the first oscillator signal and the communication signal. The second mixer may be configured to receive a scaled version of the first oscillator signal and to output a desired frequency output signal based on the scaled version of the first oscillator signal and the filtered signal.
