High-frequency system installation requirements

In Electronic Infomation Category: H | on February 01,2012

High-frequency systems typically have the following installation requirements.

(1) should be installed to minimize the frequency of coupled systems should be reduced wiring installation, layout caused by inductive coupling and AD7715AR-5 datasheet and capacitive coupling, this must reduce the wire length and AD7715AR-5 price and diameter; increase parallel squat from between the wires; as much as possible the introduction of a large dielectric constant, dielectric loss of insulating material and AD7715AR-5 suppliers and a large metal structures. In order to reduce the coupling between the wire, the wire should not be tied into a line of high-frequency Sapporo, various wires and high-frequency wire should not be parallel to 90. Crossover.

(2) insulation should be installed to meet the high-frequency insulation system installation should be used with the small dielectric constant, dielectric loss, high insulation resistance of the material, try not to make use of solid dielectric insulation layer, the most easy to use insulating layer of air, to maintain sufficient air gap. The use of air gap for electrical insulation, in order to prevent the carrier components to decrease corona cause the insulation, current-carrying element in the structure edges and corners should be avoided and cutting-edge. Since the air resistance at high frequency voltage strength (electric strength) decreased, so the higher the frequency the greater the air gap should be. Electronic devices for high-altitude, air pressure due to lower electric strength decline, we must increase the air gap.

(3) to maximize the long thin wire rigid wire rigidity difference in their impact on the vibration easily deformed, displacement, resulting in changes in circuit performance. Reduce the wire span (length), increasing the wire diameter, wire stiffness can be improved. When the concrete realization of additional fixed points on the wire clamp or pressure (equivalent to reducing the wire length), multiple wires can also be tied into a line bundle (equivalent to increasing the wire diameter).
