Antenna elements combine in phased-array antennas
Learn how to use patch antennas and phase shifting to create a phased-array antenna to steer RF signals.
5G research: It’s now about IoT
While talk of 6G has already started, 5G has moved into applied research. Students at WPI work with Professor Alex Wyglinski to connect IoT devices and vehicles to 5G networks.
PIN diode protects RF receivers from 600 MHz to 6 GHz
The SKY16603-632LF from Skyworks uses two diodes in an anti-parallel configuration.
Video: “Ideal” switch cuts signal losses
A MEMS RF switch from Menlo Micro helps eliminate the decision of whether to design a semiconductor or mechanical switch into your circuits. When designing a switch into a circuit, you’ve probably been faced with a tradeoff. Semiconductor switches are fast and live long, but they have relatively high RON that can produce unacceptable losses.…
IMS 5G Summit: Design challenges remain (part 2)
Part 2 continues the theme of power and efficiency in amplifiers, adding upload links, fixed access, and open RAN.
IMS 5G Summit: Design challenges remain (part 1)
Just because 5G is rapidly rolling out doesn’t mean everything works and it’s time to move on. Indeed, the design challenges are just beginning, as this two-part series from IMS 2020’s 5G Summit shows.
Module adds 5G to networking devices
The EM519x series of wireless modules from Sierra Wireless add 5G to embedded and IoT designs, with fallback to 4G and 3G.
Why 5G O-RANs need compliance and interoperability testing
Open radio-access networks promise to make 5G networks more flexible while fostering innovation, but with interoperable components comes the need for compliance and interoperability testing.
Step attenuators cover 13 GHz and 45 GHz
Digital step attenuators from pSemi let you adjust signal amplitude to meet the needs of components such as converters and filters.
