Quintech QS/QC Series Extended L-Band Splitters and Combiners

Quintech QS/QC Series Extended L-Band Splitters and Combiners 

The Quintech QS/QC Series is a configurable family of extended L-band signal-distribution products based on the proven Quintech LS splitter and LC combiner platforms. QS passive splitters distribute one RF input to multiple outputs, while QC active combiners combine multiple RF inputs into one nominally zero-loss output.

Two RF bandwidth and impedance options are available: 75-ohm models cover 850–3000 MHz with Type F or BNC connectors, while 50-ohm models cover 950–4000 MHz with SMA female connectors. Configurations range from 1×2 through 1×32, including single, dual and quad divider arrangements in a compact 1RU enclosure.

The series offers optional LNB power with selectable 13/18 VDC and 22 kHz tone or fixed 24 VDC output. Single or redundant AC and DC power configurations, power-supply status monitoring and multiple connector options allow the system to be tailored for satellite, broadcast, telecommunications and wideband RF distribution applications.
