Building 5G Small Cells Without Compromising Performance

Posted by Tim Brauner on Aug 5, 2020 8:00:00 AM

Before small cell technology took its place as a central component to realizing the promise of 5G networks, it played an important role in helping to improve the coverage and capacity of 4G. These mini base stations could be installed in discrete locations like on buildings or streetlights and became part of heterogeneous networkstogether with traditional macro base stationsto improve service in high-traffic locations such as sporting events and concert venues. In this pursuit, small cells have proven valuable for extending signal penetration and increasing wireless density and these small, lightweight devices will continue to be a key technology for the data-intensive transition to 5G.

Wilkinson Power Dividers and Feed Networks – A Brief Overview

Posted by Greg Alton on Jul 15, 2020 8:00:00 AM

The Wilkinson Power Divider, designed by Ernest Wilkinson in the 1960s, uses quarter wave transformers to split an input signal into two equal phase output signals. Since the design is reciprocal, Wilkinson Power Dividers can also be used as a power combiner. With this flexibility, they are widely used in many RF and microwave communication systems, including those with multiple channels or complex feed networks.

On-Demand Webinar: Building a 28 GHz Small Cell for 5G Applications

Posted by Tim Brauner on Jun 10, 2020 7:45:00 AM

As the demand for more network capacity, improved network performance, and more reliable coverage are all growing, operating in the mmWave spectrum is becoming an increasing more attractive option. To address this demand, the use of 28-GHz small cells, which are compact, lightweight devices mounted on outdoor equipment such as lampposts or telephone poles, is becoming a practical and affordable way to deploy 5G in the mmWave spectrum.

Microstrip Filters Deliver Small Size at High Frequencies

Posted by Peter Matthews on May 27, 2020 9:15:00 AM

When selecting a filter implementation, one factor that is common across all frequencies is optimizing the size of the filter given the application and the required performance. At mmWave frequencies this can be prove to be a particularly interesting problem, given the change in the physical dimensions of the system as one moves from say 600MHz to 38GHz.

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.

High-Reliability Microwave Component Technology Enables Space Innovation

Posted by Peter Matthews on Feb 12, 2020 6:00:00 AM

With more than 2,000 satellites currently orbiting the Earth, and that number expected to quintuple in the next 10 years, the demand for space-ready components is exponentially increasing (Figure 1). At the same time, the technology needed to control and transmit satellite data has changed from mechanically controlled parabolic or dish technology to active electronically steered arrays (AESAs).

2019: Laying the Foundation for mmWave 5G Globally

Posted by Peter Matthews on Jan 7, 2020 8:00:00 AM

Around the world, 2019 was a busy year for 5G, with standards being finalized, large networks beginning 5G operations, and mobile device manufacturers releasing 5G-capable phones. Just one year after the official launch of 5G on November 1, 2018, the Global mobile Suppliers Association (GSA) identified the launch of 50 commercial 5G networks along with 328 operators in 109 countries that announced investment in 5G. Let’s look at some of the big moments for 5G from 2019.

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.
