Intellian NJRC Ku-band Extended Mini 25W BUC w/M&C (NJT 8370UNMR) V1-2217
The Intellian V1-2217 is an NJRC NJT8370UNMR 25W GaN block upconverter for compatible maritime VSAT systems. It converts a 950–1,700 MHz L-band signal from the modem into a 13.75–14.5 GHz universal Ku-band uplink signal.
This model includes an N-type IF input, a separate DC power connection, and an RS-232C monitoring and control interface. Its compact, forced-air-cooled, IP67-rated enclosure is designed for outdoor antenna installations requiring higher uplink power and remote system management.

Description
Universal Ku-Band Uplink Coverage
The NJT8370UNMR operates across the 13.75–14.5 GHz universal Ku-band uplink range. It accepts a 950–1,700 MHz IF signal and uses a 12.8 GHz local oscillator, supporting compatible networks operating across both standard and extended Ku-band frequencies.
25W GaN Output
The BUC uses gallium nitride amplifier technology and provides at least +44 dBm of saturated output power, equivalent to 25W. Its nominal small-signal gain is 72 dB, with a specified minimum of 66 dB.
It is intended for compatible maritime satellite systems supporting internet access, voice, operational communications, and other vessel data services.
RS-232C Monitoring and Control
The NJT8370UNMR includes an RS-232C serial interface for integration with compatible antenna and terminal controls. Available monitoring and control functions include:
- RF power monitoring
- Transmit on/off control
- Alarm reporting
- Digital step-attenuator control
A built-in LED shows whether the local oscillator is locked and the required reference signal is present.
Separate DC Power Connection
The N-type female connector carries the L-band IF signal and external 10 MHz reference. Operating power is supplied through a separate MS connector.
The BUC accepts 36–60V DC, with 48V DC as the nominal supply. Power consumption is approximately 180W at +42 dBm output and may reach 230W at saturated output.
Protected Outdoor Installation
The weatherized enclosure carries an IP67 rating and uses forced-air cooling for operation within compatible stabilized marine antennas and outdoor fixed VSAT assemblies. The BUC automatically shuts down its high-power amplifier if the local oscillator loses lock or the 10 MHz reference is unavailable.
