You can only achieve the published fT figure when operating the transistor in common base configuration. In the more normal common emitter configuration this is degraded by the Miller effect.
That is why the very early transistor radios had common base mixers in them. Ian |

| More than AF is needed to specify the BC807 | 01/01/70 00:00 | |
| I use it as a switcher... | 01/01/70 00:00 | |
| Right! | 01/01/70 00:00 | |
| also.. | 01/01/70 00:00 | |
| A is for germanium | 01/01/70 00:00 | |
