Abstract :
A time-domain network analyzer with a bandwidth greater than 100 GHz was constructed using picosecond optoelectronic techniques. The S-parameters of a heterojunction bipolar transistor (HBT) with an f/sub max/ of 35 GHz were measured using this system. The results show good agreement with measurements of a similar HBT using a conventional vector network analyzer over the bandwidth of the analyzer (26 GHz). The optoelectronically measured S-parameters of the device were limited by the cutoff frequency of the device.<>
