As many developers are now considering a migration from 4G to 5G because of its performance advantages, private network developers often need to make changes to the 5G New Radio (NR) standard to meet certain demands.
6G wireless technology will be much more than just faster data rates and lower latency. Among other goals, 6G intends to address issues in security, sustainability, business, and industry.

THz technology promises to be indispensable – not only to achieve target requirements in terms of maximum throughput and extremely low latencies but also to realize intriguing novel applications.
Dielectric resonator antennas (DRAs) are a good choice for millimeter wave applications due to their low loss and high efficiency. Designing the resonator for a fundamental mode can be complex due to the small size and sensitivity of the resonator to fabrication errors. In this example, a larger cylindrical dielectric resonator is simulated in XFdtd to show how the excitation of the higher order modes HEM113 and HEM115 can be used to produce wide bandwidth and good gain performance.
Return loss in a wired or wireless transmitter is the ratio of transmitted power to reflected power when power is being delivered to a load. It is a critical parameter that describes transmission efficiency and can be used as an indicator that excessive power is being reflected from a load back to the source. In a wireless transmitter with poor antenna return loss, a high level of reflected power can damage the power amplifier that is driving the antenna.
To ensure the efficiency and reliability of high-power wireless charging applications such as electric vehicle charging stations, wireless power transfer circuits need stable, high-capacitance, high-voltage capacitors to serve as the tank capacitor in the LC resonant circuit.
RF field probes are required for measuring the intensity of radiated RF fields. The use of a field probe may seem straightforward, but numerous aspects can affect the accuracy of RF measurements.
The QPQ1063 is a L1/L2 GPS diplexer in a compact size for use in any GPS application. Designed for rejection of unwanted GPS signals, this SAW diplexer also has excellent power handling capability for low power transmitters.
JFW’s Model 50PMA-114 is a 5 port transceiver test system operating 30-3000 MHz in a 19 inch rack mount enclosure. There are 10 paths in the 5 port mesh and every path has its own individually controlled programmable attenuator.
