TSU Work for teaching - S-Parameters

Directional couplers

Above is part of a system built for laboratory practical work. Two Narda 20dB directional couplers, operating at up to 1GHz, are used to assess the input and output characteristics of a high frequency bipolar transistor.

After setting up the measuring instruments a plot of any of the four S-parameters of the transistor can be made against frequency.
