Temex, one of the worldwide leaders in the field of high-performance Time and Frequency components and sub-systems, announces the launch of an integrated duplexer for CDMA450 Systems in a 5x5 mm package.
A technological step forward highly integrated duplexer --
Already n°1 supplier of CDMA450 Saw Filters, Temex is launching a new duplexer, the key RF component for CDMA Handsets. The development of new SAW chips and the use of integrated passive devices is a new step in the miniaturization, particularly challenging at low Radio Frequency. Temex has now integrated a complete duplexer in a hermetically sealed package just slightly larger than a single SAW filter.
Temex : the first SAW manufacturer matching the level of performance required by the 3GPP2 international standard --
This new duplexer -TMX DU W307- replaces two individual SAW filters and three passive components, with clear advantages such as :
• High level of integration, which simplifies the CDMA450 handset design
• Cost Saving : 1 device instead of 5
• Board space saving : PCB surface 4 times smaller
• Totally lead free : compliant with RoHs regulation 2002/95.
This CDMA450 duplexer is designed to allow handsets to meet the 3GPP2 specifications, particularly the Single Tone Desensitisation Test. This new duplexer has already been approved and referenced by the major CDMA chipmakers thanks to :
• Its isolation level superior to the competition by more than 10dB
• Its power handling superior to 1Watt for a life time of over 5 years
A cost-effective and smaller solution to be fast time to market --
“Thanks to this CDMA450 duplexer, we offer our customers a smaller & highly integrated solution to be fast time-to-market. The board space is 4 times smaller saving 75mm2 and the number of components is reduced from 5 to 1. This new duplexer will help handset manufacturers reduce their total BOM cost and the size of theirs products “explains Exael Alexander, Business Development Manager. To date, no competiting products meet the 3GPP2 specifications and Temex is the only manufacturer to achieve this breakthrough technical performance.
