Abstract
The invention discloses a power bearing capacity testing method for a surface mounting passive microwave circuit. The testing method includes the steps of calculating peak current in a simulation mode when power of a to-be-tested microwave circuit set breaks through, choosing a short circuit transformer, connecting the short circuit transformer with the to-be-tested microwave circuit set to form a loop, obtaining short circuit current distribution of the to-be-tested microwave circuit set to find out a microwave circuit U corresponded by the position of the largest short circuit current, accessing the microwave circuit U to the loop to obtain the short circuit current distribution, and measuring out nominal voltage of the microwave circuit corresponded by the position of the short circuit current and a power bearing capacity value on the condition of short circuit peak current. The testing method divides a short circuit test under total power into a low-voltage large current test and a short circuit test of a single to-be-tested device under high voltage, so that test of the microwave circuit power bearing capacity can be finished on a low-power test platform through a simulation method and an analogue method, and the testing method is suitable for the batch test and is beneficial for improving production efficiency of the surface mounting passive microwave circuit.
