AN ADAPTIVE PROTECTION CIRCUIT FOR A POWER AMPLIFIER |
摘要 |
A radio frequency device comprises a radio frequency (RF) power amplifier (PA) operably coupled to a protection circuit for minimising voltage standing wave ratio effects, wherein the protection circuit comprises a current limiter indexed to a power supplied to the RF PA. In this manner, the protection circuit combines detection of both current and voltage increase in order to provide a direct feedback on the final RF PA stage via a bias control. |
