Patent abstract
An RF receiving circuit that selectively attenuates a received RF signal before it reaches sensitive modifying devices, such as a low noise amplifier or an analog to digital converter. The receiving circuit includes a delay element upstream of its attenuator so that high energy pulses of a short duration (for example, less than 10 nanoseconds) can be effectively attenuated despite coupler, detector, threshold and/or switch delays of the attenuation related circuitry.
