Intellian Terrasat Ku-band 200W (IBR137145-2NA201WW) VCM-1502
The Intellian VCM-1502 is a Terrasat IBUC G 200W block upconverter for compatible high-power maritime and fixed VSAT systems. Model IBR137145-2NA201WW covers the full 13.75–14.5 GHz Ku-band uplink range and converts a 950–1,700 MHz L-band modem signal for satellite transmission.
The integrated GaN amplifier provides 200W typical saturated output and at least 100W of linear output. Ethernet, RS-232/485, and FSK monitoring and control support remote configuration, status checks, and system integration in commercial vessels, offshore facilities, broadcast links, and network hubs.
Satellite Phone Store supplies Intellian and Terrasat maritime VSAT components. Our team can help confirm antenna compatibility, RF frequency requirements, AC power availability, and control interfaces before ordering.
Description
Full Ku-Band Frequency Coverage
The IBR137145 configuration operates across the 13.75–14.5 GHz full Ku-band uplink range and accepts a 950–1,700 MHz IF signal. Its non-inverting frequency conversion uses a 12.8 GHz local oscillator, supporting compatible satellite networks operating across standard and extended Ku-band frequencies.
High-Power Multicarrier Transmission
The VCM-1502 provides approximately +53 dBm, or 200W, of saturated RF output. Its minimum linear output is +50 dBm, equivalent to 100W, making it suitable for compatible multicarrier satellite links that require substantial usable transmit power.
Typical applications include:
- Commercial maritime broadband
- Cruise and offshore connectivity
- Broadcast contribution links
- High-capacity operational networks
- Fixed satellite gateways and network hubs
Actual link performance depends on the antenna, modem, satellite network, service configuration, and operating conditions.
Integrated Monitoring and Control
The Terrasat IBUC platform combines the block upconverter, solid-state amplifier, power supply, and management functions in one outdoor unit. Standard monitoring and control options include:
- Ethernet through an RJ45 connection
- HTTP, Telnet, and SNMPv2c management
- RS-232/485 through an MS-type connector
- Handheld terminal support
- FSK monitoring multiplexed over the transmit IF cable
Automatic gain control maintains output stability, while the internal power detector supports remote transmit-level monitoring.
AC-Powered Outdoor Installation
This 200W configuration operates from 200–240V AC at 50 or 60 Hz and consumes approximately 1,400 VA at saturated output. Its weather-resistant design is intended for installation near or within a compatible outdoor antenna assembly, reducing RF loss between the BUC and feed system.
