Abstract
Abstract A phase shifter, detector and/or modulator for superhighfrequency waves includes a two-terminal reactance network whose inductive branches consist of short linear conductors, measuring a small fraction of the free-space wavelength of an oscillation to be controlled, and whose capacitive branch or branches are lumped condensers; the network is terminated in a diode, with or without a large-capacitance series condenser, which can be selectively blocked or unblocked by the application of a suitable biasing potential to vary its impedance between a very high and a very low value. The components of the network are mounted on a conductive block received in a cutout of a two-conductor or three-conductor line strip.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
246 words
A microcircuit assembly for controlling high-frequency waves, comprising: a reactive two-terminal network provided with a pair of input terminals, said network including a linear conductor having one end connected to one of said input terminals, a grounded base connected to the other of said input terminals and a shunt condenser connected between said base and an intermediate point of said conductor, said intermediate point dividing said conductor into two portions which define respective inductive series arms of a T section having a capacitive shunt arm constituted by said condenser; a terminal impedance for said T section connected between said base and the other end of said conductor, said impedance including a diode having a capacitance on the order of that of said condenser; circuit means including a strip line and an input condenser on said strip line for connecting said input terminals across a source of high-frequency oscillation, said circuit means comprising a strip line with at least two parallel conductive layers separated by insulation, one of said layers being coupled by way of said input condenser to said conductor at said one of said input terminals, the other of said layers being galvanically joined to said base at said terminals; a further linear conductor connecting said one of said layers to said base, said further conductor having a significant inductance at the frequency of said oscillations; and biasing means connected to said terminal impedance for varying the ability of said diode to pass said oscillations.
