M.T.Faber, W.K.Gwarek [1] and S.A.Maas [2] introduced to use standard rectangular metal waveguide fabricating microwave mixer. We attempt progressively using nonradiative dielectric waveguide ( NRD-guide ) to replace metal wave-guide. Thus a kind of Ka-band NRD-guide integrated receiver front-end is presented in this paper. This integrated receiver front-end has many advantages, for example, structure simple, noise figure tow, and so on. It will find many potential applications in radar, communication and navigation systems.
