The 125W Dual Amplifier Booster and Dual Amplifier Combiner Modules are inte- gral components of Communi- cation Component Inc.?s PCS GSM-EDGE Cell Booster System. The Cell Booster System provides the means to add capacity or increase the cover- age area and penetration of existing GSM-EDGE sites.

The 125W Dual Amplifier Combiner (DAC) module combines multiple GSM channels onto a common an- tenna port without suffering any combining losses. Consequently, capacity of ex- isting sites can be expanded with the existing cabling and antenna infrastructure. The 125W Dual Amplifier Booster (DAB) module significantly increases the downlink power of the Base Transceiver Station (BTS). When used in conjunction with a Tower Mount Amplifier (TMA), the Dual Amplifier Booster can significantly increase the footprint of rural sites and improve in-building penetration in urban locations.
