VSWR and impedance, Part 5: Making a match
Understanding the role and implications of impedance in RF transmission lines and antennas is vital to successful system performance. The importance of impedance matching, minimizing reflections, and keeping a low VSWR means these topics have been studied extensively, ranging from analytical perspectives through many physical designs and implementations. This section looks at some matching techniques. […]
Q/V-band phased-array satellite antennas target next-generation satellites
A new phased-array user terminal is specifically designed for operation in the higher millimeter-wave (MMW) frequency bands for evolving next-generation communication satellites. The new low-profile antenna, based on ThinKom’s patented VICTS (Variable Inclination Continuous Transverse Stub) technology, will operate in the Q- and V-band frequencies (37.5-42.5 GHz and 47.2-51.4 GHz). These bands have been designated […]
5G and COVID-19 changed semiconductor test
In this video, 5G Technology World spoke with Marvin Test CEO Steve Sargeant about how the company adapted to mass production of mmWave devices and how the pandemic changed its methods of technical support.
VSWR and impedance, Part 3: Implications
Understanding the role and implications of impedance in RF transmission lines and antennas is vital to successful system performance. The previous sections looked at the basics of impedance and VSWR. This section looks at the implications of VSWR measurements. Q: Why should I care about reflected waves due to impedance mismatch and resultant non-unity VSWR? […]
5G mmWave brings PCB manufacturing challenges
5G can be up to 100 times faster than 4G with 100 times higher data capacity and latency of under one millisecond. What does this mean for PCBs?
VSWR and impedance, Part 2: Reflected power
Understanding the role and implications of impedance in RF transmission lines and antennas is vital to successful system performance. Part 1 of this article looked at the basics of impedance matching and power transfer. This part looks at the closely related topic of nominal impedance and VSWR. Q: Why all this worry? Aren’t RF systems […]
