Transistor Test Fixture with Integrated Couplers and Method / 14/541,622

Friday, November 14, 2014

Microwave transistor test fixtures, both micro-strip and coaxial, include integrated wideband directional signal sensors/couplers and allow the detection of the main signal and its harmonic components, injected into and delivered by a transistor in high power operation mode, by using a phase-calibrated network or signal analyzer and allows this way the reproduction of real time signal waveforms. The fixtures are best calibrated using equivalent TRL calibrated fixtures allowing overcoming the incompatibility of the internal ports connecting to the transistor terminals with coaxial cables attached to VNA
