Mini off-air band-selective LTE B3 repeater, +23 dBm, no NMS
The full parameter table below is taken from the official datasheet. The PDF version — with dimension drawings and the complete standard-compliance table — is released on request, so we can send the exact revision your project needs.
Kingtone JIMTOM® LTE B3 Off-air Band Selective Repeater Datasheet (EN, 3 pages)
Overview
Downlink signals from the base station are received by the donor antenna and amplified to the service antenna; the uplink is received at the service antenna, amplified through a low-noise amplifier and an uplink PA, and retransmitted to the base station. Band and working bandwidth are configured in software rather than by changing hardware.
- Low-gain mini format — 302 × 220 × 60 mm, under 6 kg
- Off-air band-selective: band and working bandwidth are configured in software, so the same platform covers different band plans and bandwidth slices
- AGC and ALC with 30 dB attenuation in 1 dB steps
- Frequency and bandwidth tuning both feasible
- Local keyboard and LED for gain setting
- IP55 enclosure for indoor and sheltered installation
- No NMS — for single-site fill-in where remote monitoring is not required

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 gives the working frequency range (1760–1780 MHz uplink, 1855–1875 MHz downlink) and says it is customisable. That range is narrower than the full B3 band allocation (1710–1785 MHz uplink, 1805–1880 MHz downlink) — the two are different things and should not be quoted interchangeably.
- The datasheet frequency row reads "1760-1780 MH" with the trailing z missing; read as 1760–1780 MHz.
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.
