Systems and methods for generating a microwave signal using two millimeter-wave frequencies. A first millimeter-wave up-conversion frequency, which is generated from a lower frequency source, is used to up-convert a baseband and/or intermediate signal into a first millimeter-wave signal, which is then down-converted into a microwave signal using a second millimeter-wave down-conversion frequency generated from the same lower frequency source. Each of the first and second millimeter-wave frequencies is associated with a phase noise that is higher than a phase noise associated with the lower frequency source, however, the frequency differential between the first millimeter-wave frequency and the second millimeter-wave frequency is free of the higher phase noise, as a result of the two millimeter-wave signal being generated from the single lower frequency source, thereby causing the resultant microwave signal to be free of the higher phase noise as well.
