- The SiGe HBT full S-parameters from 250MHz to 325GHz under multiple bias conditions are presented for the first time.
- Standard calibration and de-embedding techniques are used and remained valid up to 325GHz thanks to a reduction of the test structures dimensions.
- A simple and accurate small-signal electrical model was extracted and compared with measurements up to 325GHz.
