I am reading through the excellent book "Solid State Design" by Wes
Hayward et al. I have a specific question on Class C amplifier. On
chapter 2 Fig 15, a Clas C amplifier is shown with a buffer amplifier
link coupled in front.

Why is link coupling needed here, can't the collector be directly
connected to the base? It is for impedance matching or is there any
other motives behind this structure?
