FRC0750 Active L-band Combiner and Upconverter

The FRC0750 Active L-band Combiner and Block Upconverter is primarily designed to bring together several L-band carriers in a single satellite channel. To equalize the level of the incoming signals, each input has its own amplifier/ attenuator. The FRC0750 can also be used as an active switching device for signal routing purposes or redundancy switching operations.

Features of the FRC0750

• Advanced monitoring and control
• Each input is switchable and gain adjustable
• Optional upconversion to C, Ku or DBS-band

The FRC0740 L-band Block Upconverter is a High Performance frequency
Block Upconverter designed for a wide range of Broadcast, Telco and IP
satellite applications. The FRC0740 translates
frequencies from L-band to a wide range of RF frequencies such as C-, Kuand DBS-band.
The FRC0740 guarantees the best signal quality thanks to a very high frequency stability and very low spurious characteristics. It is the ideal solution
when the Block Upconverter cannot be included in the modulator. The
FRC0740 has a 30-dB variable gain control on one L-band input and one
L-band monitoring output. There is a second input with fixed 10-dB gain.
The signals on the two L-band inputs can be combined inside the unit
before being up-converted. The high output frequency stability is provided
by an internal 10 MHz reference clock. For applications requiring a very high
frequency stability (such as for very low data rate carriers), an optional very
high stability reference clock can be ordered.
The FRC0750 Active L-band Combiner and Block Upconverter is primarily designed to bring together several L-band carriers in a single satellite
channel. To equalize the level of the incoming signals, each input has its own
amplifier/ attenuator. The FRC0750 can also be used as an active switching
device for signal routing purposes or redundancy switching operations. In
its default configuration, the FRC0750 combines up to four different L-band
signals into one L-band signal. As an option it is possible to combine up to
eight different L-band signals within the same unit. A DC power supply and
a reference frequency are also available on the L-band output, providing a
compact and cost effective solution when the FRC0750 is used in combination with an outdoor RF upconverter and/or amplifier. The FRC0750 can be
delivered with an integrated block upconverter as an option. In this configuration, the FRC0750 converts the L-band output signal of the combiner to C-,
Ku- or DBS-band.
Both the FRC0740 and FRC0750 are easy to operate and monitor. All control
and monitoring parameters are available locally on the front panel and remotely through a web interface. It is also possible to control or monitor the
FRC0750 via our proprietary RMCP protocol or via SNMP.
