Intermodulation suppression for fh ( frequency hopping ) receiver is designed by selecting the intermediate frequencies and changing group of filters, local oscillation ( lo ) frequency, bandwidth of lo frequency under the condition that receiver configuration, sensitivity, dynamic range, instantaneous bandwidth and precision of frequency measurement are fixed
摘要針對跳頻接收機的體制和靈敏度、動態范圍、瞬時工作帶寬、測頻精度等設計參數，通過改變預選器組成、本振頻率和本振帶寬，分析接收通道的中頻選取原則，以實現跳頻接收機的互調抑制設計。 -
Since the envelope of modulated signal fluctuates, these methods generate unwanted intermodulation distortion ( imd ) products in a nonlinear radio frequency ( rf ) power amplifier ( pa ). so it is necessary to use linearization technique to reduce the adjacent channel interference ( aci )
但包絡變化的調制信號經過非線性射頻功放后會產生交調分量，因此必須採用線性化技術來減少由此產生的鄰道干擾。 -

With each other the lose the true intermodulation distortion department to point to be lost by enlarger a kind of importation signal for into of with and badly really. for example, at input frequency to enlarger to 1 the khz with 5 khzs admixture signal empress, would then produce 6 khz 1 khz with 5 khz it with and 4 khz 1 khz with 5 khz it bad of with each other the lose the true composition
互調失真intermodulation distortion系指由放大器所引入的一種輸入信號的和及差的失真。例如，在給放大器輸入頻率為1khz和5khz的混合信號后，便會產生6khz 1khz和5khz之和及4khz 1khz和5khz之差的互調失真成份。
