Figure 5b Transmit/Receive Equaliser Responses: Highband
The CMX644A utilises two internal equalisers - one is configured for the High Band, the other for the Low
Band. The Transmit and Receive paths will be internally switched through the equaliser appropriate to their
HI/LO BAND settings. In the event of both Transmit and Receive paths being set to the same band, both
equalisers will be bypassed.
