RF & Wireless Table 1: SunAR’s DAS antenna list * optional connectors include 7/16 DIN and 4.3-10 ping increase the coverage throughout areas hindering RF signal strength, or over use of available bandwigth. Figure 7, is just one example of a DAS solution in an office building setting. Table 2: ARI RF amplifiers for DAS application package with two RF connectors. This design provides polarization diversity in a MIMO environment. This configuration results in greater throughput than a single antenna. Conclusion: The rapid growth in connected devices (IoT) promises lucrative business opportunities. In places where traditional distribution services cannot provide the required signal strength, DAS can be used. By deploying a robust and economical DAS system, governments or businesses can ensure robust support for IoT within their facilities and be positioned to deliver critical wireless services now and in the future. The amplifiers and antennas described in this application note meet these demanding requirements, and more. Figure 5: LP425PCB LP6530PCB LP6560PCB 400 MHz – 3 GHz 650 MHz – 3 GHz 650 MHz – 6 GHz nications signals. These antennas are etched onto a low-loss microwave substrate material and mounted in a weather resistant housing that is only 1/2“ inch thick. Like the LP425R, the broadband characteristics of the enclosed antenna structures enable it to operate over a very wide frequency range with constant gain. There are four mounting holes for installation onto any flat, non-conductive surface, such as an office wall or ceiling. Figure 5 shows the LP425PCB, LP6530PCB, and LP6560PCB. The MIMO (multiple input, multiple output) antenna, shown in Figure 6, is actually a set of two broadband directional antennas, cross-polarized, in a single Figure 6: LP6530PCB-MIMO 650 MHz – 3 GHz Each antenna is innovative and uses manufacturing techniques that result in long-lasting strength and performance. Specifications for each DAS model are shown in Table 1. ARI offers Class A solid-state, linear, robust and versatile broadband RF amplifiers, see Table 2. These high performing RF amplifiers allow DAS systems to cover a large number of communication bands, hel- AR’s wide array of amplifiers and antennas help you select the right system for your application. These amplifiers and antennas are designed using quality processes and components that are reliable, consistent performance from unit to unit, and allow for easy installations in a wide variety of situations, both indoor and out. Using ARI DAS solutions will enable you to achieve your goals. To learn more about ARI DAS solution, visit our website at www.arworld.us. ◄ 68 hf-praxis 4/2019

RF & Wireless BER Test Functions for more efficient Verification of 400GbE Transceivers and DSP Anritsu Corporation www.anritsu.com Anritsu Corporation enhanced its Signal Quality Analyzer-R MP1900A BERT with the introduction of four PAM4 BERT options adding multichannel synchronization, multilane FEC pattern generation for 400GbE, Inter Symbol Interference (ISI) stressed signal generation to simulate transmission path losses, and application software for capturing device under test (DUT) error counts. The new options allow engineers to more accurately and efficiently evaluate the bit error rate (BER) of 400GbE transceivers and devices, as well as DSP used by high-speed interfaces in data centres to reduce development time and speed time-to-market. The new test functions for the PAM4 pulse pattern generator (PPG) in the MP1900A provide engineers with a singleinstrument solution for current standards, as well as emerging technologies. With the options installed, the PPG supports required 400GbE transceiver PHY layer FEC tests, as well as QSFP-DD, and OSFP, making it well-suited to verify newly designed transceivers supporting multilane technologies for PAM4 signal transmissions. It can conduct legacy jitter tolerance and input sensitivity measurements, as well as key tests on the impact of crosstalk due to use of multiple channels and error correction. To assure interconnectivit between interfaces defined by the 400GbE standards, the PAM4 PPG now has a built-in function for simulating signals after transmission through a PC board. This new capability, which eliminates the need to prototype multiple PC boards to test transmission path losses, as well as the ISI function allow for more efficient testing. A built-in function for communicating with the DUT IC error-check function has also been integrated into the MP1900A. The added capability simplifies jitter tolerance measurements during early-stage development of high-speed devices. The hardware options complement the Error Counts Import function of the MP1900A application software that allows the DUT built-in error-check function measurement results to be displayed on the MP1900A screen. It simplifies IC error measurements and creates a jitter tolerance measurement system for efficient BER tests during IC development. ◄ Frontend for universal 5G Deployments Skyworks Solutions, Inc. introduced Sky5 LiTE - the industry’s first fully integrated frontend solution for mass tier 5G cellular applications. With improved RF performance in a uniquely compact package, Skyworks’ newest device simplifies designs, enabling faster deployment. The baseband agnostic platform supports up to 100 MHz wide bandwidth of 5G new radio (NR) waveforms with flexible power management options - delivering highspeed network experiences with optimized efficiency and near zero latency. Targeted for mass markets, Sky5 LiTE interfaces with all leading chipset providers and equips early 5G adopters with differentiated architectures for an open ecosystem – the favored approach when compared with closed, sole-sourced RF front-end products. With the recent introduction of Sky5 Ultra for premium applications, Skyworks offers the most comprehensive 5G portfolio in the market. All Sky5 solutions support new 5G NR waveforms and spectrum in addition to enhanced carrier aggregation and 4G/5G dual connectivity, while delivering exceptional levels of integration and performance.
