Method and apparatus for controlling RF spectral interference into adjacent channels in an RF transmitter.

摘要

A simple and effective "RF snubber" circuit (34) resolves the problems associated with transient spectral noise caused by radio transmitter (10) activation in nearby channels. By connecting an RF snubber circuit (34) in parallel with the RF amplifier (16) output, the rise time or turn-on characteristic of the RF signal generated by the transmitter (10) is controlled. As a result, adjacent channel interference is substantially eliminated. <IMAGE>
