To meet demand for additional bandwidth for cellular and broadcast operations, national regulators are reallocating spectrum previously used for other applications. Before a new network can be rolled out within these frequencies, it is critical for the new license owner to confirm that all legacy users have terminated their transmissions. P/N: 11410-01154

5G mobile communications systems use multiple connections to meet the need for increases in mobile data traffic volumes as well as new functions such as ultra-low-latency.
3GPP determining the standards released the 5G NR non-standalone (NSA) specifications for making connections via multiple radio technologies, such as LTE, in Release 15 in June 2018.
Release 15 presumes the use of frequency bands up to 52.6 GHz and specifies the band from 450 MHz to 6 GHz as FR1 (Frequency Range 1), and from 24.25 GHz to 52.6 GHz as FR2 (Frequency Range 2). FR1 assumes use of the same wired tests as conventional wireless technologies whereas FR2 assumes OTA (Over the Air) testing.
This application note references the 3GPP TS38.104 and TS38.141 Conformance Test specifications, and introduces TRx test measurement examples for wired connections with sub-6 GHz base stations covering FR1 using the Signal Analyzer MS2850A and Vector Signal Generator MG3710A.

There are various methods for geo-locating an RF signal of interest. Primary alternatives include Power of Arrival (POA), Time Difference of Arrival (TDOA), and Angle of Arrival (AOA). In most situations where modulated signal bandwidths are greater than 25 kHz, TDOA provides the best accuracy. This application note focuses on the use of TDOA as a means for tracking a signal.

To ensure good network performance, operators and technicians must verify PIM performance at both the 600 and 1900 MHz uplink frequencies when transmitting two 600 MHz tones. Testing outlined in this document shows that mitigating PIM issue on 600 MHz band does not guarantee the same for the 1900 MHz band. Testing PIM at both frequency bands is imperative in order to mitigate PIM issues in the field. P/N: 11410-01125

RF technologies are reaching into ever more areas of our lives and the RF spectrum at all frequencies is becoming more crowded. In addition to the spectrum demands of cellular systems sub-6 GHz for mobile applications, 5G radios are now being deployed at 28 GHz and 39 GHz. 5G radios are implementing new technologies including Active Antenna Systems that use beamforming to maximize range and efficiency. This is forcing changes to the way networks are tested, including a move toward over-the-air testing and use of test model waveforms. This eBrief will discuss how 5G Radios can be tested in a field environment and what measurements are important to ensure smooth integration with legacy networks. P/N: 11410-01130

Vector network analyzers (VNAs) are used to measure the performance of a wide variety of passive and active RF and microwave devices. Passive devices can be less demanding to test than active devices, thus requiring less performance from the VNA. However, one interesting exception to this is the measurement of very low insertion loss passive components such as precision adapters or airlines. These types of devices can present a difficult challenge to characterize because of the desire for very low uncertainties on these small insertion losses. This application note talks about these challenges and provides a helpful technique. P/N: 11410-01090
