Quellan Incorporated, based in San Diego, California, is a privately held company that develops analog integrated circuits (ICs). The firm's products improve enterprise network and mobile device signal quality. The company's Q:ACTIVE (TM) ICs are embedded in enterprise network line cards, switch cards, backplanes, and cabling. The modules extend signal ranges from 12 to 30 meters. The products reduce power consumption and simplify system management. Quellan is known for its QLx serial interconnect lane extension, QHx radio frequency (RF) harmonic suppression, and QNx narrowband noise cancellation products. Noise cancellation systems are offered in integrated microcontroller and IC versions. The firm's QHx100 harmonic suppression device reduces input-output interference in the 800MHz to 1.6GHz RF range. A filter and driver circuit suppress clock harmonics. The unit's bypass mode reduces power consumption. Quellan's lane extension devices reduce noise in data center equipment and interconnects. The units support Infiniband, PCI Express, 10GBase-CX4, SAS, and other standards. Quellan's 5bar (R) technology boosts the signal strength of wireless handsets, game consoles, Global Positioning System devices, and other consumer electronics products.
