Technical Field

[0001] This utility model belongs to the technical field of radio frequency switch dispensing equipment, specifically relating to a radio frequency switch dispensing fixture and radio frequency switch dispensing equipment. Background Technology

[0002] Radio frequency (RF) switches are common components in RF circuits, used to switch between different signal paths, including receiving and transmitting, switching between different frequency bands, and switching between different antennas. They are widely used in mobile phones, base stations, satellite communication systems, etc., facilitating antenna sharing and cost savings. After RF switch production, a dispensing process is required. However, existing RF switch dispensing equipment uses general-purpose fixtures for clamping and fixing, or fixtures used in testing and assembly processes, such as test fixtures. For example, the CN217766539U test fixture for a single-pole double-throw RF microwave switch includes a placement stage with a placement slot on its upper side, a movable stage on the upper side of the placement stage, an inner frame on the inner side of the movable stage, a clamping plate on the inner side of the inner frame, and an adjustment slot inside the movable stage.

[0003] Existing general-purpose fixtures and clamping jigs have limitations in terms of the number of units they can hold, only one RF switch at a time, and the ability to constrain only one or two locations on the RF switch. This results in poor stability and affects dispensing accuracy. Furthermore, the clamping jigs are not designed specifically for dispensing, which can lead to the problem of the jigs covering the dispensing area of ​​the RF switch during clamping. Utility Model Content
