Quintech QS 75-Ohm Extended L-Band Splitter and Combiner Series, 850–3000 MHz

Quintech QS 75-Ohm Extended L-Band Splitter and Combiner Series, 850–3000 MHz 

The Quintech QS 75-Ohm Series is a configurable family of extended L-band signal-distribution products operating across 850–3000 MHz. It includes passive and active RF dividers as well as active combiners for satellite, broadcast, telecommunications and centralized signal-distribution systems.

Available configurations range from single, dual or quad 1×2 and 1×4 units to single or dual 1×8 and 1×16 models and a single 1×32 configuration. All models use 75-ohm Type F or BNC female connectors and fit within a compact 1RU enclosure.

Active configurations provide nominally zero-loss performance and up to 15 dB of input gain. Signal-level and amplifier-status monitoring over Ethernet support remote supervision. Optional LNB power, adjustable 13/18 VDC output with 22 kHz tone and fixed 24 VDC power are available.

Single or redundant AC and DC power options allow the QS Series to be configured for both standard signal-distribution systems and higher-availability installations.
