Vancouver, Canada-based Norsat International, a provider of intelligent satellite solutions, had announced the launch of a new line of Band Pass Filters (BPF) designed to mitigate WiMAX (News - Alert) terrestrial microwave interference on satellite reception.

“As WiMAX network deployments continue to expand globally so will their interference with satellite communications,” said Dr. Amiee Chan, president and CEO at Norsat International (News - Alert), in a release.

He said that with ongoing research and development in both WiMAX and satellite communications, “Norsat is exceptionally well positioned to address the industry demands these competing technologies present.”

In addition to rejecting frequencies outside the range of 3.7GHz to 4.2GHz, the new BPF-C Band Pass Filter is also expected to reject frequencies outside the range of 3.625GHz to 4.2GHz.

Designed for customers requiring a narrower filter to address a more precise frequency, the new narrow filter, BPF-C-BW36 Band Pass Filter, officials said, will pass through only ±18MHz on either side of the customers specified Center Frequency.

Officials said that the new BPF-L Band Pass Filter is designed to provide additional filtering that may be required at L-BAND to prevent modem saturation.

Norsat International designs, engineers and markets intelligent satellite solutions for high-speed data transmission. The company’s portfolio of capabilities include: microwave components; fixed, transportable, ultra-portable, vehicle-mounted and maritime satellite systems; turnkey maritime navigation and communications systems; and end-to-end network services.

Last year in October, company established a WiMax business unit to pursue satellite-enabled WiMax opportunities in emerging markets throughout Asia, Africa and South America.

Also last year in July, company launched the first product in its new vehicle mount satellite terminal family, and signed contracts with the U.S. military and an unnamed Asian broadcasting network, to provide vehicle mount terminals for the transmission of video data feeds.
