Abstract
Apparatus and methods for RF signal limiters with diode-enhanced limiting are provided. In certain embodiments, an RF signal limiter includes a field-effect transistor (FET) stack electrically connected between an RF signal path and a limiting node, such as ground. The FET stack includes a first or topmost FET having a drain connected to the RF signal path. The gate of the topmost FET is biased through a first gate resistor. The RF signal limiter further includes a first forward enhancement diode having an anode connected to the RF signal path and a cathode connected to the gate of topmost FET.
