RF bipolar

Wow, the first entry to talk! The article mentions RF CMOS as the follow-on to discrete bipolar circuits. Was there no RF bipolar integrated (even if not at LSI level) in between? Companies like National made a lot of linear ICs, some of which could be used in RF circuits, at least at the lower end of RF. Gah4 (talk) 06:20, 12 December 2019 (UTC)[reply]

Well, there is the RFIC article, which deals with RF integrated circuits in general. It's a stub at the moment, but the article could be expanded to include a general overview of RF bipolar, RF CMOS, and maybe GaAs as well. Maestro2016 (talk) 08:46, 12 December 2019 (UTC)[reply]

OK, there is the National Semiconductor Linear Data Book from 1988.^[1] Chapter 2 is radio circuits, including most of an AM/FM radio. It seems to have all of the non RLC circuits for an AM radio, and everything after the mixer for FM. It needs an FM RF amplifier and mixer, and all the tuned circuits externally. Chapter 3 has an RF modulator for TV signals, including both audio and video. Not so fancy compared to what you find today, though maybe what you find in AM/FM radios, but not so bad, either, and much more advanced than discrete transistors.
