Q band up-converter

A packaged up-converter has been developed for the ETSI 42 GHz point-to-point radio band. The MMIC contains an LO-doubler-buffer amplifier, an image-reject balanced mixer and an RF variable gain amplifier. The up-converter has 10 dB conversion gain, 15 dB image rejection, 15 dB of gain control, 15 dBm IIP3 and 50 dB LO-to-RF isolation in the mixer. The up-converter consumes less than 1 watt DC represents the state of the art in performance, integration and cost.
