摘要： A distributed RF/microwave power detector for detecting the power of a signal is provided. The distributed RF/microwave power detector includes a power detector on or at least partially embedded in a single substrate. The distributed RF/microwave power detector includes a detection unit that has a distributed amplifier for amplifying the signal and outputting an amplified signal, and a detector for detecting the power of the amplified signal. The distributed RF/microwave power detector further includes at least one additional detection unit cascaded with the first. The additional detection unit includes an additional distributed amplifier for amplifying the amplified signal and outputting a further amplified signal, as well as an additional detector for detecting a power of the further amplified signal. The distributed RF/microwave power detector also includes a multiplexer for multiplexing outputs of the detector and at least one additional detector, each having a dynamic range different from the other.

摘要： An infinite position door hold open includes a pair of pivotally interconnected hinge members which are respectively mounted on the door and body. The door mounted hinge member pivotally supports an arcuate link having oppositely facing braking and frictional surfaces, both generated about the pivotal axis of the hinge members. The braking surface is frictionally engageable with a brake pad adjustably mounted on the body mounted hinge member. The engagement of the braking surface with the brake pad is controlled by pivotal movement of a wedging cam relative to the door mounted hinge member between non-wedging limit positions through an intermediate wedging position. The cam has a friction member in constant engagement with the frictional surface of the brake member. Any reversal of the direction of movement of the door relative to the body causes the friction member of the cam to move the cam to the intermediate wedging position and wedge the braking surface of the brake member into frictional engagement with the brake pad.
