Abstract: A structure for transmitting signals of PCI express and a method thereof provides a converting device and a high-definition multimedia interface (HDMI) cable. The converting device has a plug connector to into a PCI express slot, along with a HDMI connector. The signal converting circuit connects the signal pins of the PCI express slot to the signal pins of HDMI connector. One end of the HDMI cable is connected with the HDMI connector of the converting device. The present invention can extends the signal distance of the PCI express to exactly perform the signal test.

Abstract: A loop coupled microwave cavity, which uses a cylindrical cavity as the main body and has a lock hole on the top of the cavity in order to connect to a loop-coupling end formed by bending the long pin of an SMA connector. The long pin of the SMA extends into the cavity through the lock hole so that the top end of the long pin will touch the inner wall of the cavity to receive a microwave signal in TM012 mode to excite the cavity. On the other hand, the coaxial structure formed by the long pin and the lock hole is a quarter-wavelength transformer, so the SMA connector has both loop coupling and impedance transforming functions to increase the Q factor of the cavity. A diminutive sample is inserted into the cavity to perform the cavity perturbation method (CPM).
