Kingtone JIMTOM® B28+B8+B3+B1+N78 End BDA 20260720 datasheet
Overview
The front end of the six-band multi-operator fibre coverage system. It sits behind the donor antennas and combines the operator signals of five bands into one fibre path before the power splitter feeds the master units. B28, B8, B3, B1 and N78 are handled here; WiFi is carried by the remote units rather than the front end, which is why the model code reads 28/8/3/1/78 and not /W/. One set of equipment replaces one repeater chain per operator and band.
- Combines five bands (B28 / B8 / B3 / B1 / N78) and several operators into one fibre path — one set of equipment for multi-network integration
- Uplink amplified to +20 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 output power row is cut off at the N78 entry, so the N78 output figure is not quoted here even though the band is listed.
- The intermodulation row is cut off after the 9 kHz – 1 GHz figure; the 11 GHz – 12.75 GHz figure that follows it could not be read.
- The mechanical and power block (dimension, weight, power consumption, operating temperature) could not be read from the .doc file — it is not quoted rather than estimated. Ask us for the figure before quoting it.
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.
