From the 1920s to the 2020s – Bandwidth Has Always Been King

Posted by Peter Matthews on May 13, 2020 8:00:00 AM

Over time, the telephone replaced the telegraph, and now cellular and voice over Internet protocol (VoIP) technology are replacing the landline. However, as more communication is done wirelessly and over the Internet, we are becoming more interested in increased bandwidth. This is because bandwidth places a limit on how quickly we can send information through a channel such as an optical fiber or a section of the radio spectrum.

The Challenges 5G Brings to RF Filtering

Posted by Peter Matthews on Oct 29, 2019 9:51:00 AM

In the race to implement mainstream 5G wireless communication, the world is waiting to see if this next-generation network will achieve a hundredfold increase in user data rates. This transformative technology not only boosts performance for the latest cell phones, but also for fixed wireless access (FWA) networks and Internet of Things (IoT) smart devices. In order to reach 10 Gbps peak data rates, the increase in channel capacity must come from somewhere. A key innovation at the heart of 5G is utilizing new frequencies greater than 20 GHz in the millimeter wave (mmWave) spectrum, which offers the most dramatic increase in available bandwidth.

RF Filtering Techniques for Millimeter Wave Applications

Posted by Peter Matthews on Aug 6, 2019 3:59:00 PM

The millimeter wave (mmWave) part of the electromagnetic spectrum is at the high end of the microwave region, which spans ~300 MHz to 300 GHz, and is usually taken to mean frequencies from ~30 GHz to 300 GHz and wavelengths in the range of 1mm to 1cm (Table 1). This dramatically increases available bandwidth, thus expanding achievable data rates, which makes these frequencies extremely interesting to teams around the world working on fifth generation (5G) communications.
