For filter details also observe table 8-1 Digital filters (narrowband) for Class A repeaters
or table 8-2 Digital filters (broadband) for Class A repeaters , respectively.
Center Freq. Setting: Set up the Center Freq. per each channel.
Center Freq. Range: 758.000000 ~ 775.000000 (MHz) Ref: DL Freq.
Digital Gain Setting: DL/UL gain control per each channel *
Digital Gain Control Range: +/- 5 dB in steps of 0.5 dB
Start Freq.: Calcuate Center Freq - (Bandwidth/2) (display Only)
Stop Freq.: Calculate Center Freq + (Bandwidth/2) (display Only)
* An additional gain offset between -5 and +5 dB can be set for each defined channel to compensate
components with frequency-dependent insertion loss, e.g. external filters or splitters. The end-to-end
gain (total system gain) including external components (not antennas) must not exceed a gain of 90 dB
.
If you require more detailed information with an example of an end-to-end gain equation, ask our
Technical Support (for contact data, please refer to chapter
1.6.1 ).
