The Key Role of Multiband Combiners and Band Separators
I've written a lot in this column about interference and for good reason: it's a bigger issue now then ever for commercial and public safety wireless systems -- and is getting worse. However, wireless carriers also face the continuing challenge of reducing costs wherever possible, from the device level straight through to the antenna. Multiband combiners and separators and bandpass combiners are invaluable components that not only reduce costs but reduce system complexity as well. These versatile products allow the transmit and receive signals from several wireless bands to be multiplexed into a single antenna, eliminating a variety of components and helping to reduce the growing rat's nest of cables within single-carrier or co-located sites. These bands can be either within a single wireless frequency allocation, such as 700 MHz, or different bands, for example GSM and PCS, including both uplink and downlink frequencies for each network. As their core components are cavity filters, they retain the superb performance of this filter type, including extremely high rejection and isolation along with the ability to handle very high output power levels. Anatech has been designing and manufacturing bandpass combiners and separators for more than 20 years have met the most challenging requirements. In addition to standard products available at AMCrf.com, we can quickly build custom designs to handle any wireless band from VHF through microwave frequencies, as well as weatherproofing for outdoor installations and other special requirements.
