Today’s shift towards faster 4G networks has transformed our world with entirely new mobile apps with higher connectivity. In the growing Internet of Things, these faster networks are extremely important for the seamless transfer of high amounts of data. 5G networks are the future technology that will connect the world we live in.
High peak-to-average power ratios (PAPRs) are not beneficial as they challenge the non-linear power amplifier operation close to compression in order to reach maximum efficiency. Possible solutions for include crest factor reductions (CFR), such as clipping high signal peaks. This video demonstrates a simple technique to clip any waveform, including the Verizon Wireless 5GTF signal, with the use of software tools for signal generation and analysis.

As 5G testing continues to grow and demand more requirements for filtering components. Corry Micronics (CMI) has developed all types of filtering using different technologies, and several that have been allocated for 5G. At lower frequencies in the US market centered around 600 MHz, filtering can be easily, and cost competitively designed using several different filtering technologies. Types of filters range from LC to cavity, combline, interdigital, Helical, ceramic resonator, and tubular.
Antenna engineers favor advanced antenna systems capable of beam steering and multiple data stream transmission in order to meet 5G throughput requirements. Designing such a device is a difficult task because many factors are involved a device’s performance:

Next-generation 4G/5G telecommunication systems require power amplifiers (PAs) to operate with high efficiency over a wide frequency range to provide multiband and multi-standard concurrent operation. This application note describes the design of an innovative Doherty amplifier architecture using 200-W high-efficiency broadband 1.8-2.7 GHz GaN high-electron mobility transistor (HEMT) technology, which achieved average efficiencies of 50-60 percent for output powers up to 100 W and significantly reduced the cost, size, and power consumption of the transmitters. The designers used the NI AWR Design Environment platform, specifically Microwave Office circuit design software.
Every time a new cellular phone standard comes out, we see new claims about the “end of Wi-Fi.” When 3G was announced, the promise was that it would make Wi‑Fi (802.11b) redundant, which clearly turned out to be incorrect. With 4G (LTE), this story repeated itself and claimed it would put Wi‑Fi (802.11ac) in the shredder. And now the 5G message is that it will cover both the inside and outside of homes and buildings. It’s almost as though Wi‑Fi will soon no longer be needed. This begs the question: What will be the impact of the next generation of Wi‑Fi, Wi-Fi 6 (802.11ax)? Do we even need it in the 5G/wireless landscape? This article discusses the answers.
Corry Micronics offers an array of components for 5G network filtering applications.
New technologies being deployed will need to rely on the performance of both high-power amplifiers on the transmit side, and low noise amplifiers on the receive side. Quantifying critical specifications like noise figure and noise power ratio can give radio and receiver designers a deep understanding of how the overall system will perform. Noisecom noises sources generate the broadband noise required to do this type of benchmarking and quantify component and system performance across the microwave and millimeter bands.
