Attached is a plot of the gain on the interval 50-3000 MHz (ref -20dBm = 0). It has been verified with a spectrum analyzer with tracking generator (-40dBm input). It does not correspond to the announced gain. Certainly not monotonically decreasing with frequency.

動作していますが、仕様やdBを確認するためにオシロスコープで測定されていませんが、平均して信号の有無を調べていると思います

It works, but not yet measured with oscilloscope to confirm specifications and dB but I think they are in average looking at signal with or without it
