PolyPhaser DAS AISG protocol compatible Bias-Tee.

PolyPhaser introduces the DAS product platform that combines world class lightning suppression and 3G/AISG functionality. The fully AISG compatible DAS product line is built to serve the remotely controlled antenna line device (ALD) market on UMTS 3Gequipment.

The DAS-HY is a wide band 800- 2500MHz device comprised of a bias-tee current injector, lightning protector, and RS-485 AISG modem. It works by

receiving an RS-485/DC signal from a Remote Control Unit on the RCU/DC portand multiplexing it onto the RF feeder cable. The DAS-HY incorporates an EMP protection device that protects the DC circuit separately from the RF/Data streamprotection.

Other devices in the DAS series are the DAS-TP for twisted pair protection, as well as, the DAS-BT, which is a Bias-Tee with integrated lightning protection. Customized solutions are available.
