The required couplers are integrated together with a pair of mixers in one single ceramic package, making extensive use of the multilayer capabilities of the host substrate. The module operates in a frequency range from 18 - 32GHz with acceptable conversion loss, yielding an image rejection of more than 14dB in a band from 18.5 to 25.5GHz.enAllgemeines, WissenschaftConference PaperConference Paper
