    Abstract: A test apparatus and method of testing a DUT are described. The apparatus includes a receiver and transmitter path each having a pair of switches that switch between a bypass position and a direct position. The bypass position is used for low frequency signals communicated through the apparatus. The direct position allows higher frequency signals to be double converted by upconversion to an IF signal and bandpass filtered before being downconverted to a predetermined frequency. Both variable and fixed LO signals are used to convert the double converted signals so that the same IF may be used independent of the higher frequency signal received or transmitted. Bandpass filtering is applied before and after amplification of the IF signal. Lowpass filtering before and after the double conversion use LPFs of different cutoff frequencies.

    Abstract: A microelectronic test device comprising an organic substrate, a probe holder, and an interposer disposed between the organic substrate and the probe holder, wherein the interposer has a coefficient of thermal expansion that is less than a coefficient of thermal expansion of the organic substrate. The interposer may effectively decouple the organic substrate from probes in the probe holder, which may substantially reduce or eliminate probe misalignment due to the coefficient of thermal expansion mismatch between the organic substrate and other components of the microelectronic test device and to provide require stiffness to the organic substrate.

    Abstract: In one embodiment, a device to test one or more electronic components comprises a first card comprising a first test device communicatively coupled to at least a first connector assembly positioned on the first card and a second card comprising a second test device communicatively coupled to at least a second connector assembly positioned on the second card. The at least a first connector assembly is directly communicatively coupled to the at least a second connector assembly to provide a direct communication interface between the first test device and the second test device that is not routed via a backplane. Other embodiments may be described.
