    摘要: An (M+1)-for-M redundant switch, where M is an integer greater than 1, is provided. The (M+1)-for-M redundant switch includes a first switch-triad-assembly including a first switching element circulator and two element isolators; a second switch-triad-assembly including a second switching element circulator and two element isolators and; and at least one inverted-switch-triad-assembly including a third switching element circulator and two element isolators. One of the element isolators of the first switch-triad-assembly is arranged to couple power with one of the two element isolators of one of the at least one inverted-switch-triad-assembly. One of the element isolators of the second switch-triad-assembly is arranged to couple power with another one of the two element isolators of one of the at least one inverted-switch-triad-assembly.

    摘要: A waveguide circulator which does not cause an arcing phenomenon and deterioration of microwave characteristic, even when a ferrite member generates heat to raise a temperature thereof. The waveguide circulator is composed of a waveguide formed substantially in Y-shape with rectangular waveguides which are provided so as to position horizontally on a predetermined plane, and further they are extended in different three directions from junction positions of the waveguide wherein two ferrite members are placed in the junction positions thereof so as to oppose to each other on the upper and lower sides in the height direction perpendicular to the predetermined plane wherein an extended section extending in the height direction in the vicinities of the junction positions of the waveguides is formed, and a distance between the ferrite members is expanded to compensate decreased impedance.

    摘要: Switchable circulator comprises a ferrite element (101) with a first segment (102-1) a second segment (102-2) and a third segment (102-3) extending in respective first, second and third directions from a center portion (104) of the ferrite element. Each of the first segment (102-1), the second segment (102-2), and the third segment (102-3) include a first channel (106) located at a first distance (L1) from a center point of the ferrite element and a second channel (108) located at a second distance (L2) from the center point. The first and second distances (L1, L2) define a first and second resonant sections of the ferrite element. Thus, the switchable circulator can be configured to selectively operate in two different frequency bands.

    摘要: A radar system having a tactical mode and a calibration mode includes a transmitter section (30) for providing high-power amplification of an RF pulsed waveform from an exciter during the tactical mode and the calibration mode. A circulator system (40) has an input port connected to an output of the transmitter section and including first, second and third switchable junctions (C1, C2, C3), and a high-power attenuator (46). The circulator system provides a transmit tactical mode signal path (42) and a transmit calibration mode signal path (44) of virtually identical electrical path lengths for a transmitter output signal, the tactical path passing through the first, second and third junctions in a first direction to an antenna I/O port, the calibration path passing through the first, second and third junctions in a second direction and through the high-power attenuator to an output port. A receiver section (50) is coupled to the output port and includes a receive tactical mode signal path (72) through a low noise amplifier (LNA), mixer, and an intermediate frequency (IF) amplifier to an IF output port for down-converting a radar signal. The receiver section further includes a receive calibration mode signal path (74) through an attentuator which bypasses the LNA and passes through the mixer and IF amplifier to the IF output port.
