HP 11602B transistor fixture

Product Description

HP 11602B Transistor Fixture – For S-Parameter Measurements, DC to 2 GHz

This used HP 11602B is a precision transistor test fixture designed for S-parameter measurements from DC to 2 GHz in a 50-ohm coaxial circuit . It is specifically engineered to mount directly on the front panel of the HP 8745A S-Parameter Test Set, providing a complete solution for characterizing bipolar and field-effect transistors .

The fixture accepts transistors with TO-5 to TO-12 package dimensions, as well as any three or four-lead package with leads that lie on a 0.2-inch circle and have diameters of 0.016 to 0.019 inches . It can also be used to measure other circuit elements such as diodes, resistors, or inductors with appropriate lead dimensions .
