Glossary of RF Path Terms

We’ve put together a blog post compiling a RF path glossary with a list of terms that are commonly used in radio frequency applications. Alternating Current (AC) An electrical current that changes polarity (i.e., direction) 50 to 60 times per second. It offers significant efficiencies when transmitted across power lines, making it the standard current […]

Maximizing Capacity With Microwave Backhaul

Network capacity and managing demand Simply put, capacity is a network’s ability to handle transmission traffic. In the case of cell communications, this traffic means voice and data – often, a great deal of data. As capacity demands continue to rise with the spread of long-term evolution (LTE) and 4G mobile devices, smart planning becomes […]

Interference Isolation Techniques for Transmitters and Receivers in Antenna Systems

Achieving sufficient isolation The correct degree of isolation between transmitters and receivers can be implemented by one of two methods: 1) Use two antennas, physically separated by a given distance, or; 2) Use the appropriate duplexer with a single-antenna system. Let’s examine the first option of two physically separated antennas. Within this option, there are […]

How To Overcome Interference Challenges In Duplex Communications?

How isolation helps overcome challenges in duplex communications? In duplex RF systems, transmitting and receiving frequencies are close to each other. In addition, the antennas will also be physically close, or even share a single antenna. This results in two main sources of interference  – receiver desensitization and transmitter noise. How can we overcome these […]

Isolating Sources Of Interference In Wireless Systems

Example Sources of Interference: An RF communications system that employs simultaneous, two-way flow of voice, data or other information is called a duplex system. Duplex communications systems combine multiple transmit and receive channels on a shared antenna, with information flowing both ways at the same time. Imagine the simultaneous flow of traffic on a busy […]

Amplification Methods For Co-Siting Solutions

Amplification: Another technology that makes co-siting possible is amplification. There are several ways amplification can be used in support of the co-siting devices, expanding their utility, power and range. Single carrier power amplifier: One of the hybrid combiner’s drawbacks is its high rate of insertion loss for both TX and RX signals. One way to […]

Co-Siting Solutions: Multi-band and Same-band Combining

What is Multi-Band Combining? Multi-Band Combining is a method of frequency multiplexing. It takes advantage of the fact that feeder cables are naturally well suited to being shared by multiple frequency bands. In other words, multiple base station services can be funneled into a single feeder cable that runs up the tower to the antennas. […]
