Embodiment Construction

[0017] see Figure 1a , which is a schematic diagram of the substrate surface circuit structure of the electrical parameter adjusting device according to the first embodiment of the present invention. The substrate 4 can be a PCB board (resin substrate), a ceramic substrate or a plastic substrate and the like, and the substrate 4 can be a single-layer, double-layer or multi-layer substrate. In this implementation, the substrate 4 selects a double-layer circular (not necessarily circular, but also polygonal and other graphics) PCB board, and there are at least two access terminals on the surface of the substrate 4. The present embodiment is 12 Access terminals 11, 21, 31, to 121. A first device C1 , C2 , C3 , to C12 is respectively connected between each access terminal and the ground terminal 100 . The ground terminal 100 is connected to the ground terminal on the bottom layer of the substrate 4 through a metal via 101 . The first devices with different electrical parameters...

Abstract

The invention relates to an electrical parameter adjusting device which comprises a substrate, at least two accessing terminals, a ground terminal, a positioning member and a first component, wherein the at least two accessing terminals, the ground terminal, the positioning member and the first component are manufactured on the substrate. The electrical parameter adjusting device is characterized in that at least one accessing terminal is connected with one end of the first component, the other end of the first component is connected with the ground terminal, a signal accessing terminal and a ground terminal are manufactured on the positioning member, the accessing terminals on the substrate contact with the signal accessing terminal on the positioning member, the ground terminal on the substrate contact with the ground terminal on the positioning member, the next accessing terminal on the substrate is enabled to sequentially contact with the signal accessing terminal by changing the position of the substrate, and the ground terminal on the substrate is always kept contacting with the ground terminal on the positioning member.

Description

technical field [0001] The invention relates to an electric parameter adjusting device, which is mainly applicable to the fields of various electronic circuits, radio frequency circuits and their systems. Background technique [0002] In the field of electronic components, various variable inductors, variable capacitors, variable resistors, and variable attenuators have been widely used. In electronic circuits, especially in radio frequency circuits, these variable devices are required to be smaller in size and shorter in size at the signal access end, so that their radio frequency characteristics can be better and their applications wider. On July 28, 2008, I applied for a patent for an electric parameter adjustment device, the patent application number: 20081044258.3. Although it realizes the adjustment of the radio frequency device, and can make the path of the radio frequency signal of the device to be adjusted the shortest, which can reduce the radio frequency loss. H...
