I am not into radio, but i thought a PIN diode is used to get a variable
capacity by changing the bias point.
This does NOT require a fast diode, the bias is changed quite slowly.
I do not doubt it can be used as pin diode, but this does not make it a
fast diode.
a 1n4007 is a slow mains frequency rectifier diode.
