Abstract
We propose a compact quasi-optical scheme to achieve image separation using two mixers. With this scheme, an image rejection ratio of better than 12 dB has been obtained over 25 GHz in W-band without any mechanical tuning. This diplexing scheme should find applications in remote sensing and radioastronomy
