Radio frequency detector for test chamber
Radio frequency detection circuitry includes a radio frequency (RF) emitting device; a waveguide to receive RF energy emitted by the RF emitting device; a power detector to convert RF energy received by the waveguide to a voltage; and a safety device that operates if a threshold voltage is detected at the power detector.
1. Radio frequency detection circuitry comprising:
a radio frequency (RF) emitting device;
a waveguide to receive RF energy emitted by the RF emitting device;
a power detector to convert RF energy received by the waveguide to a voltage; and
a safety device that operates if a threshold voltage is detected at the power detector, wherein the safety device is outside of a test chamber indicating that the RF energy is being transmitted within the test chamber.
