Transistor Test Fixtures
MT950 Series The MT950 transistor test fixture (TTF) is a comprehensive measurement system for convenient and accurate characterization of packaged microwave transistors from DC to 18 GHz. The system consists of the basic test fixture, MT950B2 or MT950G (short lead version), transistor package inserts (MT951 series), and check devices (MT953 series). A number of useful accessories are also offered with the TTF. These include an adjustable height stand (MT950R) to support the fixture when it is connected to a vector network analyzer such as the Agilent 8510, tools for assembling the inserts to the fixture body, tweezers for handling the devices, and spare parts. De-embedding The basic TTF and inserts manuals include circuit models which can be used to develop de-embedding parameters that allow measurements to be referenced to the device input and output planes. For S-parameter measurements, we recommend Maury's Windows® 95/98/NT compatible MT956D software. Because this application includes the TTF and insert circuit models, it can be used to de-embed S-parameter measurements made on devices in the fixture, and to develop the de-embedding parameters of other fixtures. Maury's automated tuner system software also includes these TTF de-embedding models, so all noise, power, adjacent channel power, and intermodulation distortion measurements can be de-embedded.
