Title:
CIRCULATOR/ISOLATOR TEST FIXTURE
Document Type and Number:
WIPO Patent Application WO/2019/095792
Kind Code:
A1
Abstract:
Disclosed are a circulator/isolator text fixture, comprising a ground plate, a PCB board, an adjustable capacitor and a high-frequency connector. The PCB board is provided with a microstrip circuit; one end of the microstrip is electrically connected to a plug core of the high-frequency connector; the other end of the microstrip circuit is provided with a pad; one end of the adjustable capacitor is electrically connected to the microstrip circuit; the other end of the adjustable capacitor is electrically connected to a ground line on the PCB board; and the PCB board and the high-frequency connector are respectively fixed on the ground plate. The circulator/isolator test fixture provided in the present invention is provided with an adjustable capacitor. Before testing the performance of a circulator/isolator, a user can utilize the adjustable capacitor to adjust overall standing waves between a high-frequency connector and a PCB board, so that a test environment of the circulator/isolator reaches a perfect state, thus test data of the circulator/isolator is more precise and is more reliable. The structure is simple, machining is convenient, and manufacturing costs are low.
