Method and apparatus for controlling RF spectral splatter into adjacent channels when activating an RF transmitter

摘要

A simple and effective "RF snubber" circuit resolves the problems associated with transient spectral noise caused by radio transmitter activation in nearby channels. By connecting an RF snubber circuit in parallel with the RF amplifier output, the rise time or turn-on characteristic of the RF signal generated by the transmitter is controlled. As a result, adjacent channel interference is substantially eliminated.
