  • Patent number: 10097165
    Abstract: Compact, high Gamma, wideband, multi-carriage-multi-harmonic tuners use a meandering slabline structure and multiple probes and carriages. The meandering structure reduces the overall tuner length by more than half at 0.4 GHz. The required slabline bends are made using a vertical-to-horizontal slabline transition. Multiple probes are employed within the slabline segment closest to the test port, in order to minimize the insertion loss at higher frequencies, caused by the slabline bends. This tuner structure is mostly effective starting at fundamental frequencies below 1 GHz and operating at fundamental or harmonic frequencies as high as 18 GHz.

  • Patent number: 10084424
    Abstract: A device and associated method for adjusting electrical impedance based on contact action are disclosed. The device includes a drive unit (1), a contact unit (2), a monitoring unit (3), and a control unit (4). The monitoring unit (3) measures an impedance signal of an electromagnetic functional material (7) in an alternating-current circuit, and transfers the impedance signal to the control unit (4). In response to the impedance signal measured by the monitoring unit (3), the control unit (4) controls the drive unit (1) to apply a mechanical load on the contact unit (2), which causes the contact unit (2) to contact the electromagnetic functional material (7). The value of a contact load is adjusted, so as to adjust the electrical impedance of the electromagnetic functional material (7), thereby achieving the objective of adjusting the impedance matching in the alternating-current circuit in real time.
