The module has separate 3G / 4G / 5G PA blocks operating in the mid- and high bands, a silicon controller containing the MIPI® RFFE® interface, RF band switches, MB and HB antenna switches, bi-directional couplers, and integrated filters for Bands 1, 2, 3, 7, 34, 39, 40 and 41.

  3. Wireless Communications For Automotive Applications 4/14/2022

    Providing enhanced comfort and safety are motivating designers to advance several communications technologies, especially the eCall introduction and the first direct communications scenarios. Rohde & Schwarz provides a wide range of test solutions for all vehicle-based applications, including safety and comfort, among many others.

  4. Planar Filter Technology For mmWave Applications 3/21/2022

    Planar filters are manufactured by creating flat 2D resonators with patterns of strip elements on a dielectric substrate. Depending on the filter topology, planar filters can offer a high quality factor (Q) and a reasonable approach to achieving performance in a small footprint. 

  5. RF Technology For The 5G mmWave Radio 2/22/2022

    As the arrival of 5G gets ever closer, it continues to generate challenges for designers. When determining the best technology solution for mmWave radio applications, it is beneficial to consider all aspects of the signal chain, as well as the various advantages of different IC processes.

  6. Brochure: R&S®AMS Aerial Monitoring System 2/14/2022

    The R&S®AMS aerial monitoring system is a payload for drones that provides monitoring and analysis capabilities for VHF/UHF/SHF transmissions that are difficult to reach by conventional mobile or handheld solutions. Typical applications include monitoring of microwave links and interference hunting in dense urban environments.

  7. Bring Us Your Toughest Challenges 2/4/2022

    At Knowles Precision Devices, we purposely avoid commodity components. What we thrive on is doing the hard things. We handle the specialty components that go in systems that cannot fail and that operate at extremely high voltages, temperatures, or frequencies.

  8. Striking A Balance For Spectrum Needs: 5G Communications Vs. Aircraft Altimeter Operations 2/2/2022

    On Jan. 19, 2022, many international airlines canceled or delayed flights to major US airports where they believed 5G signals could possibly interfere with the radar signals required to properly operate landing equipment on their planes. Working through this potential interference issue is critical because 5G is not going anywhere.

  9. 5G User Equipment Power Amplifier R&D Testing 2/2/2022

    5G New Radio (NR) presents dramatic challenges to the testing of User Equipment (UE) Power Amplifier (PA). This application note introduces an example of automated testing of 5G UE PA with R&S signal generator, signal and spectrum analyzer, vector signal explorer software, and power meters/power supply.

  10. When To Use Frequency Selective Power Sensors 2/2/2022

    When characterizing highly complex wireless signals such as those used in 5G, there is a need to measure individual signals in the presence of nearby spectral content. As with an RF receiver, frequency-selective measurements filter out nearby signals, thereby reducing noise and improving measurement sensitivity. This can be advantageous when characterizing low-level signals at cellular base stations or satellite ground stations.
