RF PA oscillation problems can be broadly categorized into two kinds:
Bias oscillations and RF oscillations.
Bias oscillations occur at low frequencies, in the MHz to VHF range, and are caused
by inappropriate and unintentional terminations at those frequencies by the bias insertion circuitry, such as the addition of a large-value decoupling capacitor.
The oscillations have little to do with the details of the RF matching circuitry, where the RF blocking and decoupling capacitors become open circuit terminations at lower frequencies.
RF oscillations, on the other hand, typically occur either in the band or commonly out of the band but are still quite close to the desired bandwidth from the low-frequency side.
Decreasing the low-frequency gain of a PA stage, which is naturally at an increased level, will assist in amplifier stability.
The unavailability of a sufficient ground plane or a ground plane that is excessively segmented can create uncontrollable instability in a PA.
