Abstract: A low cost, vibration resistant high frequency switch (10) includes a conductive housing (16) having bores for receiving a center probe (40), first and second cantilevered side probes (42, 44), a floating center contact and a dielectric control rod (76). The center probe includes an axial bore (60) in one end which loosely receives a first end of the low mass, wire shaped axially extending center contact (64). Adjacent the opposite, second end (66) of the center contact (64), free ends of the side probe are spaced in a longitudinal direction perpendicular to the axial direction and extend from opposite directions into overlapping relationship with the floating center probe positioned therebetween. A solenoid (12) controls the dielectric control rod which engages the center contact approximately midway along its length to selectively force the second end into engagement with the first or second side contact while maintainig engagement between the first end (48) of the center contact (64) and the center probe (40).

Abstract: An electrically-controlled electromagnetically switching device (10) for controlling the flow of current between a plurality of pins (20, 22, 24). The switching device (10) includes a base (12), an input pin (20), first and second output pins (22, 24), an actuator (78), a magnetic field generator (16), and generator pins (28). A reed (78) and actuators (14) are movable between a first position which electrically connects the first output pin (22) and the input pin (20), and a second position which electrically connects the second output pin (22) and the input pin (20). Dielectric compatible plastic material with enhanced plastic shielding is located in apertures in the base (12), to retain the pins (20, 22, 24) therein.

Abstract: An improved switching arrangement (20) for waveguide is disclosed which comprises, in combination, a coaxial switch (12) and a unified, multiport, waveguide interface (14). The coaxial switch (12) has coaxial connectors of a first type (12a', 12b', 12c') mounted in a parallel pattern with a preestablished center-to-center spacing. The waveguide interface (14) includes flanges (14a', 14a'', 14b', 14b'', 14c', 14c''), and is preferably formed as a waveguide housing having a transition plate portion and a cover plate portion. Each port of the unified waveguide interface includes internal waveguide-to-coax transitions for coupling to a respective external connector of a second type. The external coaxial connectors (16a, 16b, 16c) are configured in a parallel pattern with center-to-center spacings of the coaxial switch connectors (12a', 12b', 12c') such that these connectors mate directly with those of the unified waveguide interface. By so doing, intervening coaxial cables or adaptors are eliminated and relatively low insertion loss and fast switching speed are exhibited over a relatively broad bandwidth.

Abstract: A low power level RF signal (applied at Port 1) is processed by a network formed of capacitors (30, 32), inductor (28) and resistor (24) which adds a DC offset level (applied at Port 3) thereby effectively increasing the power level of the RF signal. External switching circuits connected to the offset signal will be more responsive to the signal due to the effective power elevation.
