초록

A new design technique of fabricating 40 GHz up-converter modules for digital microwave radios has been developed. The design of the up-converter module is based on unit circuit blocks, which are to be characterized using a special test fixture. The complete module design may be as simple as a cascade layout of these unit circuit blocks. Also, the 40 GHz up-converter module employs a new microstrip-to-waveguide transition and a tapped edge-coupled filter, which are less sensitive to fabrication tolerances.
