Beschreibung
Zusammenfassung:	All the microwave components involved in generating, transmitting and receiving millimetric microwave signals, including transmit/receive antennae, are integrated on a single soft substrate, the only off-substrate connections comprising DC power and relatively low-frequency control signal paths. Circuit components include a DC blocking capacitor of which one plate is a portion of a strip transmission line conductor (22), the other plate is the overlapping portion of an electrode (202) of a varactor diode PILL package (20), accommodated in a correspondingly-shaped aperture in the soft substrate (210), the dielectric comprising insulating tape (212). A prismatic ferrite circulator housed in a correspondingly-shaped aperture in the substrate may be employed.
