摘要： A test kit for testing a device under test, DUT, (130) includes a socket structure for containing the DUT (130). The DUT includes an antenna (AT) and radiates a RF signal. The test kit further includes a reflector (230) having a lower surface (230b). The RF signal emitted from the antenna (AT) of the DUT (130) is reflected by the reflector (230) and a reflected RF signal is received by the antenna (AT) of the DUT (130).

摘要： A transmission interface between at least a master module and a slave module is proposed. The transmission interface includes a predetermined number of physical transmission medium(s). Each physical transmission medium is arranged to carry a multiplexed signal in which at least two signals are integrated, and the predetermined number is not smaller than a number of intermediate frequency (IF) stream(s) to be transmitted.

摘要： A matching network circuit (10) for RF power amplifier circuit capable of odd harmonic rejection and even harmonic rejection in the differential mode and the common mode, respectively. The matching network circuit (10) includes a differential mode filter (C 1 ) with a differential resonant frequency and a passive component (L 1 ) coupled to a virtual short circuit node (B) at the differential mode filter, wherein a common mode filter with a common resonant frequency includes the differential mode filter (C 1 ) and the passive component (L 1 ). As a result, two notch filters with different resonant frequencies are utilized for the common mode and the differential mode, respectively.
