Powerwave Honored with Second Award for WiMAX Product Excellence

(Product News, 30 Jul 2008)

Powerwave Technologies Inc.'s Universal WiMAX Digital Radio Head (DRH), has been named a winner of a 2008 WiMAX Distinction Award presented by integrated global media company Technology Marketing Corp. (TMC).

The 2008 WiMAX Distinction Awards honor companies that are able to demonstrate a commitment to innovation in the WiMAX space. TMC's editorial staff chose the winners based on exemplary products and services developed and deployed during the past year.

"Our Universal WiMAX Digital Radio Head continues to garner accolades throughout the industry as one of the most innovative products for increasing the coverage and capacity of WiMAX networks," says Khurram Sheikh, Chief Product and Development Officer, Powerwave Technologies. "We are honored that TMC has chosen to honor us with a WiMAX Distinction Award in 2008. This award further validates our continued commitment to supplying complete hardware, software and services that not only reduce capital and operating expenditures, but also increase wireless network performance."

Designed for operation with next-generation base stations, Powerwave's universal WiMAX DRH is an IEEE 802.16e transceiver, featuring Common Public Radio Interface (CPRI) electrical or optical interfaces, which can be optimized for customer specific applications. The CPRI interface supports redundancy and carries bi-directional signal and control data, including alarms for antenna VSWR, LNA failure, digital input overdrive, and erroneous configuration requests from the baseband unit.

Powerwave's universal WiMAX DRH offers up to 20MHz of instantaneous, multi-carrier operation. The built-in flexibility of the WiMAX DRH allows key parameters, such as channel bandwidth, output power and Time Division Duplex (TDD) ratio to be changed in order to optimize coverage and capacity, without requiring firmware upgrades. Channel bandwidth configurations of 10MHz and 10MHz + 10MHz are supported as standard, with 5MHz + 5MHz and 20MHz available as firmware upgrades.

Featuring digital channel filtering, digital up and down conversion, RF up and down conversion, power amplification, low-noise receive amplification and TDD duplexing, the WiMAX digital radio head is a high-rejection sub-band RF filter, based on Powerwave's proprietary ceramic technology. It offers exceptional unwanted signal rejection with very low loss in the TX/RX paths (26W per path transmit power, 2.5dB typical receive noise figure), and enables the unit to meet stringent out of sub-band emissions requirements, including FCC 67+10log(P) without need for external filtering, which can increase insertion loss, power level errors and cost.
