Powerwave Technologies Introduces Dual Band Antennas
Barcelona, Spain -- Powerwave Technologies, Inc., a global supplier of wireless infrastructure solutions, announced two new dual band antennas here recently at Mobile World Congress 2008.
The first offering is Powerwave's 2.0 m Dual Broadband Integrated Remote Electrical Tilt (i-RET) Antenna. Additionally, Powerwave also introduced its 1.4 m Dual Broadband Antenna with Integrated Diplexer.
Both antennas accommodate lower (824-960) and upper frequency (1710-2170) bands within the same housing, providing carriers with maximum flexibility for co-siting and capacity expansion.
The i-RET product is an industry first featuring an integrated remote electrical tilt antenna and is designed for operation in multiple bands. Separate RET modules for the lower and upper bands are integrated into a standard housing, providing the same length, width and depth as the equivalent antenna without RET. The antenna is the next iteration of Powerwave's innovative i-RET antenna product line, which integrates remote electrical tilt functionality under the antenna radome, delivering maximized functionality and improved aesthetics, while eliminating installation and reliability issues that can occur with typical exterior RET modules.
Other benefits include manual tilt functionality, extended and shifted tilt range, and maximum flexibility via support for 3GPP and multi-standard controls. Also included is absolute position sense, a feature that allows resumption of calibrated antenna tilt measurement and control after loss of power, without antenna recalibration.
Powerwave's new i-Diplexer antenna features a low loss and high power diplexer integrated inside the base station antenna. The antenna is designed for site architecture that allows combining the lower and upper frequency bands at the antenna, cutting in half the number of cable runs. This configuration eliminates the need for an exterior diplexer resulting in a more compact form factor without sacrificing performance. These benefits include improved reliability due to a reduction in the overall number of external parts, and a reduced need for cables and weatherproofing. The antenna is offered in either a MET version or with RET.
"These two new antennas are representative of Powerwave's continued efforts to integrate more functionality into the antenna with fewer separate components, to improve maintenance, installation, field service and upgrade," said Bill Vassilakis, vice president, Corporate Research and Advanced Development, Powerwave. "The result is antennas that are robust and reliable with fewer moving parts, all of which serves to lower operational costs."
