Figure 9: Transmit/Receive Equalizer Responses: Highband

The CMX644A utilizes two internal equalizers - one is configured for the High Band, the other for the Low

Band. The Transmit and Receive paths will be internally switched through the equalizer appropriate to their

HI/LO BAND settings. In the event of both Transmit and Receive paths being set to the same band, both

equalizers will be bypassed.
