Considerations When Using RX Window Filters
Considerations When Using RX Window Filters Multi-pole window filters are commonly used as front-end filters in receive multicouplers. EMR Multicouplers always come equipped with a standard multi-pole front-end filter. In contrast, other OEMs often require an...
Understanding the Importance of Reflected Power in Combiner Systems
Understanding the Importance of Reflected Power in Combiner Systems In a combiner system, power that's reflected at the antenna port doesn't make it to the antenna, instead, it is reflected back and dissipated as heat in the isolator output load termination. This...
Which Antenna Duplexer is right for you?
Which Antenna Duplexer is right for you? There are several factors involved in choosing the right duplexer for your application. Most consider only TX power and frequency offset when deciding whether a duplexer fits their application. While these factors are...
Understanding Antenna Aperture and BDA Systems
Understanding Antenna Aperture and BDA Systems Utilizing a directional antenna for a BDA donor antenna isn't just about the gain it provides, but also how the antenna narrows the aperture of the antenna. Using a directional donor antenna focuses the energy to-and from...
Cavity Filter-Ferrite vs Hybrid-Ferrite Combining
Cavity Filter-Ferrite vs Hybrid-Ferrite Combining: What's the Difference? Transmitter (TX) Combiners are designed to allow a number of transmitters to share a common antenna reducing cost as well as tower wind and weight loading. A TX Combiner needs to accomplish...
Antenna Duplexers
Antenna duplexers provide the means for simultaneous operation of a mobile relay or repeater station having separate TX and RX frequencies when using a common antenna.
