The Quintech LC 1000A Series is a family of active broadband RF combiners designed to combine multiple input signals into a single RF output.
The series is intended for applications where several RF sources need to be brought together and distributed through a common downstream signal path.
For example, a satellite ground station or telecommunications facility may receive RF signals from multiple modulators or external feeds. Instead of connecting every source through a complicated arrangement of individual cables and passive combining components, an LC 1000A system provides a centralized combining platform.
The product family includes three principal models:
The different configurations allow system designers to select a model according to the number of RF sources, rack-space requirements, and signal-distribution architecture.
All three models operate across the specified 5–1000 MHz frequency range and provide an insertion-loss specification of 0 ± 2 dB at 500 MHz.
According to the manufacturer’s documentation, the LC 1000A Series uses Quintech proprietary technology to meet demanding level, matching, and loss specifications. Custom configurations are also available.
The LC16 1000A is the 16-input configuration within the product family.
It combines up to 16 RF input signals into one output and is designed for installations with a relatively moderate number of RF sources.
Its compact 1RU rack-mount construction makes it suitable for facilities where rack space is limited.
With a maximum specified P1dB of +8 dBm per input, the LC16 1000A provides the highest per-input P1dB rating among the three configurations listed in the datasheet.
Key characteristics:
The LC16 1000A is suitable for smaller RF distribution systems that require centralized signal combining without the additional rack-space requirements of larger models.
The LC32 1000A is designed for installations requiring a larger number of RF input connections.
It supports 32 RF inputs combined into one output, making it appropriate for more extensive signal distribution systems.
Its 2RU rack-mount configuration provides additional capacity while maintaining a centralized equipment arrangement.
The manufacturer’s datasheet specifies a P1dB of +1 dBm per input, with the value identified as a single-carrier equivalent.
Key characteristics:
The LC32 1000A offers a useful balance between input capacity and rack-space requirements for medium-sized RF distribution facilities.
The LC64 1000A is the highest-capacity configuration in the series.
It supports 64 RF inputs combined into a single output, making it suitable for large-scale installations involving numerous modulators, RF sources, or external feeds.
Its 3RU rack-mount design provides a centralized location for a high number of RF connections.
The datasheet specifies a P1dB of -2.0 dBm per input for this model.
Key characteristics:
For large RF distribution systems, the LC64 1000A can help simplify cable routing and reduce the need for multiple cascaded combining stages.
The LC 1000A Series operates across a frequency range of 5–1000 MHz.
This broad operating range makes it suitable for compatible broadband RF distribution applications that require combining signals across a wide range of frequencies.
The operating bandwidth provides flexibility when integrating different RF sources into a common distribution architecture.
It is important to note that the LC 1000A Series is a broadband RF combiner, not a satellite-band IF combiner covering the full 950–2150 MHz range. Engineers should verify frequency compatibility before selecting it for a particular satellite system.
One of the defining features of the LC 1000A Series is its active combining architecture.
Quintech describes these products as active, zero-loss combiners designed to simplify RF engineering.
The specified insertion loss is 0 ± 2 dB at 500 MHz across the three models.
This characteristic helps reduce the need to compensate for the substantial signal attenuation typically associated with passive combining arrangements.
For RF system designers, this can simplify link-budget calculations and equipment selection.
The manufacturer identifies its microstrip design as an important feature of the LC 1000A Series.
According to Quintech, this design provides improved performance and reliability.
The microstrip implementation is part of the manufacturer’s approach to achieving the required RF characteristics across the operating frequency range.
The LC 1000A family is available in 16-way, 32-way, and 64-way configurations.
This allows customers to select the appropriate capacity for their installation rather than relying on several smaller combiners connected in sequence.
The manufacturer specifically highlights that larger configurations can eliminate cascading, helping improve system performance.
Reducing the need for cascading can also simplify cable management and equipment organization.
Cable organization is a major consideration in professional RF installations.
As the number of connected RF sources increases, managing individual cables and connections can become difficult.
The LC 1000A Series uses a centralized rack-mounted design to improve cable routing, access, and identification.
This is particularly useful in telecommunications facilities, satellite ground stations, and broadcast environments where equipment may need to be inspected or maintained regularly.
Frequent manual connection and disconnection can increase connector wear and the possibility of connection failures.
