BTS front-ends

- UMTS-2100
A typical front-end includes 2-way hybrid combiner with isolators, duplex filter with integrated Rx amplifier and distribution, antenna VSWR alarm monitoring and bias-T for power supply of TMAs and power supply, control electronics and alarm interface to the base station.
Front-end including auto tuned cavity combiner is also availbale. This FCU offers low insertion loss for a 4 channel combiner.
Based on our experience, Combilent offers to assist in writing the specification for complex RF products.
