Abstract
A structure for extra-high-frequency circuit modules, to take advantage of the low losses and convenience of assembly of waveguides, and at the same time to take advantage of the ease of tuning of microstrip lines. Each module is adapted to be conveniently connectable to others in a cascade arrangement, and each presents a waveguide interface to adjacent modules. If a module is to contain an active device, such as an amplifier, the module incorporates a microstrip section and two transition sections to couple the microstrip section to the waveguides at input and output. The microstrip section is easily tunable and is easier to couple to the active device.
