Packaged, Integrated 32 to 40 GHz Millimeter-Wave Up-Converter

A 4 × 4 mm QFN overmoulded packaged up-converter has been developed for the 38 GHz point-to-point radio band. The MMIC contains LO-doubler-buffer amplifier, image-reject balanced mixer and RF amplifier with linear gain control and consumes 1.5 watts DC. The up-converter has 7 dB conversion gain, 15 dB image rejection, 15 dB of gain control, 20 dBm IIP3 and 50 dB LO-to-RF isolation in the mixer. Performance is similar in the 32 GHz band. The up-converter represents the state of the art in performance and cost.
