AE02B-A3659 Rev -- DESCRIPTIONDocument use is restricted to that described on cover 1-1CHAPTER 1DESCRIPTION1.1 OVERVIEWThe SelectAmp NBPCS-900-3 bi-directional channelized paging repeater provides selective frequencyamplification of user specified frequencies in the 901-902, 930-931, and 940-941 MHz Narrowband PCSbands. The unit can be configured with up to three channelizers allowing the user to configure the unit tosuit their needs. The channelizers are available in two versions: a 930 MHz, 12.5 kHz Bandwidth versionintended for POCSAG/FLEX and a 940 MHz, 50 kHz Bandwidth version intended for ReFLEX. Frequencyselection, gain adjustment and fault monitoring is accomplished with monitor and control circuitry andfirmware.Within this manual, “Forward Channel” refers to the RF signal path from the base station to the pager andthe “Reverse Channel” refers to the RF signal path from the pager to the base station.1.2 ELECTRICAL SPECIFICATIONSTable 1-1 below contains the electrical specifications.Table 1-1 Electrical SpecificationsParameters SpecificationFrequency Range Forward (930) = 928 – 932 MHz.Forward (940) = 938 – 942 MHz.Reverse = 897 – 903 MHz.Composite Output Power Forward = 1 Watt.Reverse = 500 mWatts.Output 1 dB Compression Point Forward = 4 Watts.Reverse = 1.3 Watts.Power GainFwd ChannelsRev Channel50 to 95 dB nominal, adjustable from front panel.50 to 85 dB nominal, adjustable from front panel.Third Order Output IP3 Forward = +51 dBm.Reverse = +43 dBm.
