Bipolar transistor availability

Am I the only one wondering why production of RF transistors in SC-70 or SOT323 package is becomming obsolete at almost all vendors?

The only exceptions (without EOL) I can find is the BFU5*0 series from NXP.

Look at https://www.infineon.com/cms/en/prod...rf-transistor/
And some Chinese manufacturers supply still such RF Transistors

The reason is most certainly that the market share for these devices has shifted away, and sales to the large customers has dwindled.

Why? Because integration eats modules and PCBs
where it can, leaving the scraps.

GHz and upward, small signal, mass market really wants
integration.

Manufacturers are moving from SC-70, e.g. SOT-323/343 to QFN because the latter is cheaper. The former requires lead-forming, whereas the latter does not. Moreover the former's gull-wing leads are susceptible to bending during automated testing and is a source of over-rejection.
