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.
Quadrature Hybrids Selection Guide Quadrature hybrids are four-port directional couplers with a -3dB coupling coefficient. TRM Microwave offers high-reliability, space qualified 90° and 180° quadrature hybrids along with standard models for land, air, and sea-based military architectures.
WIRELINE And WIREPAC Design Guide This design guide includes information on configurations and coupling theory, hybrid design information, coupler design information, defined coupling terms, component selection/preparation, circuit applications and more for the Wireline and Wirepac quadrature couplers and hybrids.
Low PIM RF Switches To avoid high intermodulations levels, Dow-Key, now offers the "W" option that is designed to allow low PIM levels. The average PIM level for a multiposition RF switch is -167dBc with a 3rd order IM at -125dBm.
Passive Components Guide Narda offers a broad range of high-power passive products which are widely used in power test equipment and for military systems requirements. Many of the Narda high-power passive products are available as catalog-stock items.
Millimeter-Wave Crossguide Couplers Datasheet This datasheet contains information features, electrical/mechanical specifications, an outline drawing, and more for the CGC series of millimeter-wave crossguide couplers. These couplers are ideal for applications involving subsystems, power sampling, phase-lock loops, and built-in test equipment.
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).
This cavity notch filter has an insertion loss of 2.5 dB (max), a VSWR of 1.5, and covers the 824- to 894-MHz frequency range. Additionally, this filter has a >70 dB notch attenuation at 840 MHz to 842 MHz, 100W power handling, and 50-ohm impedance.
This presentation provides information on RLC Electronics' passive components offerings; more specifically, their coaxial switches, waveguide switches, filters, duplexers/diplexers, gain equalizers, attenuators, terminations, power dividers/combiners, couplers, bias tees, and more.
This tutorial offers information on the T3 (two-tone-terminator) High-Linearity/IP3 Mixer, and how it compares to traditional double balanced mixers from a performance standpoint. The Two Tone Terminator line of mixers has the world’s best two-tone intermodulation and spurious performance.
