Abstract

This invention discloses a mobile phone top-pinned RF calibration fixture. It includes the following steps: RF test floor, it's in cell phones, including the test pad and exposed copper pad; test needles used in the RF test, when conducted RF calibration, the top pressure is on the test pad; needle for the grounding, when conducted at the RF calibration, the top pressure on the exposed copper pad. Testing and grounding needle are acupuncture needle .Cell phone top-pinned calibration fixture includes two RF grounding pin. The structure is simple, reliable performance, low cost, easy to make; Unique RF pad design, and can fully compatible RF test Block pad design requirements; improve production efficiency; compatible long / RF short head calibration methods.

Description

technical field [0001] The invention relates to radio frequency detection of wireless communication equipment, in particular to a mobile phone thimble radio frequency calibration fixture. Background technique [0002] When mass-producing GSM (Global System for Mobile communication, Global System for Mobile Communications) mobile phones, usually, the absolute accuracy of the devices used cannot meet the performance targets of the device frequency, power level and other parameters. Therefore, it is logical that one of the ways to reduce system performance deviation is to use more expensive, higher precision, and better consistency components. However, in reality, every wireless device manufacturer deliberately provides users with cheap and high-quality products. Therefore, under the pressure of cost, they usually do not choose expensive and more precise components for design, but go In the opposite direction, RF calibration becomes an integral part of R&D and production.
