Kingtone JIMTOM® B8+B3+B1 Front End BDA, KT-A-L8L3L1-P33-B datasheet
Overview
The front end of the multi-band, multi-operator fibre coverage system. It sits directly behind the donor antennas and combines the operator signals of all three bands into one fibre path before the power splitter feeds the master units. One set of equipment carries B8, B3 and B1 for several operators, which is the point: a single fibre infrastructure and a single installation instead of one repeater chain per operator and band.
- Combines the donor signals of three bands (B8 / B3 / B1) and several operators into one fibre path — one set of equipment for multi-network integration
- Uplink amplified to +33 dBm per band while the downlink passes at 0 dBm, so the downlink is not amplified twice
- High linearity PA for high system gain
- Internal intelligent monitoring helps locate faults for maintenance
- Gain adjustability linearity: 10 dB ±1.0, 20 dB ±1.0, 30 dB ±1.5
- Weatherproof design for all-weather installation
- Compact size, flexible for installation and relocation

Indicators are based on ETSI standard testing. Availability varies depending on the laws and regulations of each country. Unless otherwise specified, all displayed specifications are typical and subject to change without prior notice.
- The datasheet does not state an environmental class (IP rating); the IP66 figure comes from the product team, not from the datasheet.
- The datasheet's mechanical and power block (dimension, weight, power consumption, operating temperature) could not be read from the .doc file — it is not quoted here rather than estimated. Ask us for the figure before quoting it.
- The intermodulation row is cut off after the 9 kHz – 1 GHz figure; the 100 kHz figure that follows it could not be read and is not quoted.
- The datasheet gives the three bands' working ranges but does not state whether the operator bands inside B8 / B3 / B1 are selected by software or by a filter. Confirm the configuration with us for a specific operator set.
Where our documents disagree with each other, we show both readings and confirm the value for your variant before you order. Tell us the model and band you need.
Certification status for this model is not recorded in this library. Do not state that it is certified without checking the certificate; ask us for the specific model number when you need the certificate.
