Laird Technologies, Inc., a designer and supplyer of customized performance-critical components and systems for advanced electronics and wireless products, has been awarded a U.S. patent for the work of three of its wireless and M2M inventors: RF Engineer III Joseph Combi, Director of Engineering Ayman Duzdar, and RF Engineer III Gary Reed.

U.S. Patent #8045592 was issued for work with multiple antenna multiplexers, demultiplexers, and antenna assemblies. The multiplexers and assemblies receive signals from the multiple antennas in a system and combines those signals for transmission into a single output. The demultiplexers receive the single input and output the signal onto separate receivers. The antennas used in this patent included GPS (1574 to 1576 MHz) and world cell frequencies (824 to 960 MHz and 1710 to 2170 MHz).

“The benefit of this technology is that it reduces the number of cables required in a long cable harness, mostly in the OEM automotive market, as they have control over the receiver,” says Ayman Duzdar. “It can also be used in tandem with a demultiplexer of the same nature to separate the combined signals into multiple receivers. It reduces cost spent on the harnesses by reducing the number of cables necessary.” The antenna multiplexers are ideal for any market where multiple antenna signals are being delivered from one antenna module to multiple receiver modules and where GPS and cell functionality is required.

Laird Technologies is a designer and manufacturer of telematics products with a product portfolio consisting of antennas and integrated reception systems designed to meet the multiple communications requirements of modern vehicles. This includes performance-critical products for wireless and other advanced electronics applications as well as electromagnetic interference (EMI) shielding, thermal management products, specialty metal products, signal integrity components, and antenna solutions, as well as radio frequency (RF) modules and wireless remote controls and systems. Custom products are supplied to all sectors of the electronics industry including the handset, telecommunications, data transfer and information technology, automotive, aerospace, defense, consumer, medical, mining, railroad and industrial markets. A unit of Laird PLC, Laird Technologies employs over 12,000 employees in more than 49 facilities located in 16 countries.
