摘要： A testing device for testing transceivers includes a transmitter operable in a first state to transmit signals, a receiver operable in a second state to receive signals and a power coupler coupling the transmitter to the receiver. The testing device further includes an overload protection device operably coupled between the power coupler and the receiver to reduce or maintain the signal strength of a received signal at the receiver based on a control signal. A controller determines a current state of the received signal and generates the control signal based on the current state of the received signal.

摘要： A system and method is designed to measure its own environmentally caused inaccuracies and, based upon these measurements, adjust itself to compensate for the inaccuracies. In one embodiment, a test system first measures the signal loss through a model “long” path constructed in the same substrate as is the main test circuit. Since the test path is constructed on the same substrate it then represents the actual environmental impact on the test circuit. The test signal is then sent through a “short” test path and the ratio difference from a reference measurement condition between the two paths yields the necessary compensation which is then used to calibrate the test circuit. In another embodiment, a test signal is applied across a capacitance made up of copper on different layers of substrate material. The actual environmental conditions on the substrate layers modify the measured capacitance value, which is then provided along with temperature as input to a model which determines compensation for the test circuit. Both embodiments can be applied to individual circuits or to systems that are subject to environmentally induced changes to their transmission line loss characteristics.

摘要： Hermeticity of microcircuit packages is achieved in one embodiment by recognition that water can penetrate the ceramic structure and thus the ceramic structure is sealed and the edges of the ceramic package are metallically bonded to the electronic package. In one embodiment, a clear ceramic dielectric compound is sprayed on the ceramic and then the package is glazed.

摘要： By adding light reflective and/or transparent and/or translucent material within a micro-electronic circuit housing, improved light transfer is achieved between a light generation source and a light utilization device. In one embodiment, the reflective material is placed on the inside surface of a non-metallic housing lid and the light from the light source (typically an LED) reflects from the reflective material and impacts the device (typically an FET). In another embodiment, the LED and FET are encased in a clear (low light-loss) material (typically silicone overcoat) so as to allow the light from the LED to reflect from the top of the clear material onto the FET. If desired, an opaque encapsulant surrounds the clear material and fills out the volume within the housing. In another embodiment, clear or translucent (as opposed to opaque) encapsulant can be used to serve dual purpose as both the structural (volume filling, defined package share/outline) agent as well as to permit the internal light transmission and reflections to illuminate the device.
