The ComFlex BDA (Bi-directional Amplifier) is a compact, 19″ rack mountable chassis that can hold up to 6 RF modules. The unit can be fed RF through a multiple of sources including BTS (Base Station) through Comba’s ACU solution, Small Cell as well as a base station’s over-the-air RF signal received through a donor antenna mounted on the roof. Designed as an affordable DAS system that can be configured for venues up to 50K square feet.
Features:
- Supports up to 6 bands of 700 Upper C/700 Lower ABC/800/850/1900/EAWS
- Supports GSM, CDMA, WCDMA, and LTE modulation
- Supports multi operator configurations and up to 3 sub-bands per band
- Operation via friendly and easy OMT interface with RJ45 connection
- Integrated Ethernet for remote monitoring and control

mBDA RF Modules
At the heart of the mBDA system is controlling and distributing the RF signals. The mBDA can take up to 6 RF modules to customize the wireless ecosystem. Just simply plug the unit in and make the connections to the antennas.
Features:
- Avaiable in 6 bands: 700MHz Upper, 700MHz Lower, 800MHz, 850MHz, 1900MHz, and EAWS.
mBDA Combiner Module
This penta band combiner fits directly into a 19″ rack simplifying the system installation. Simply connect the RF source from the donor antenna to the combiner and then to the RF modules to create a simple, clean cellular repeater system.
Features:
- Penta band combiner: 700/800/Extended PCS/AWS1&3 and WCS+2.6G.
