Page 18: Circuit Operational Description
Digital Repeater Line DSP95 Series User’s Guide 1.9 Circuit Operational Description The repeater uses a single down conversion/up conversion scheme. There are multiple RF amplifier stages prior to each down-converting mixer. The down-converting mixers are followed by a single IF amplifier. A DSP block then processes the resultant digitized IF signal that was previously generated by an analog-to-digital converter. -
