Welcome To Our Passive Components Spotlight Newsletter
|
 RF passive components may not be the stars of an RF system, but few can deny the importance of a good supporting cast of passive components. Whether it’s the splitter and combiner in the amplifier chain, attenuators to adjust signal levels, directional couplers to sample the RF signal, or switches to control signal flow, passive components play a key role in overall RF system performance. Plus, the performance requirements of passive components continue to increase to support the rising power levels, frequencies, and bandwidths of today’s RF systems. Check out the latest in passive components in our spotlight section below. |

VNAs With Wide Frequency Coverage Help Overcome High-Speed Interconnect Challenges
By Bob Buxton, marketing manager, General Purpose Test, Microwave Measurements Division, Anritsu Company
Cloud computing, smartphones, and LTE services are creating a significant increase in network traffic. To support this added traffic, speed of IT equipment — such as that used in high-end services in data centers — must be increased, creating challenges for signal integrity engineers that must be met by advanced test instruments, such as vector network analyzers (VNAs).
