Inductors only behave like inductors below because of what’s called their self resonant frequency. And the self resonant frequency arises because the equivalent circuit of real-world inductors isn’t strictly inductive. There are parasitic elements that come into play. To understand why, look at the equivalent circuit for an inductor. An inductor can be comprised of […]
Coax GaN power amps span 30 MHz to 7.5 GHz
Pasternack, a leading manufacturer and supplier of RF, microwave and millimeter wave products, announces their expanded offering of gallium nitride (GaN) coaxial power amplifiers. GaN has emerged as the technology of choice in power amplifier designs. The high power density of gallium nitride semiconductor technology dissipates heat more effectively, which results in amplifier designs that […]
Bi-directional RF amps
operate in L and S-Bands
Irvine, CA – Pasternack, a manufacturer and supplier of RF, microwave and millimeter wave products, introduces a new line of bi-directional amplifiers that are used for sending and receiving radio signals in key applications such as unmanned aerial vehicles (UAV), unmanned ground vehicles, L and S band radar, military radio, commercial air traffic control, weather […]
Broadband limiters protect
RF circuits from high-power signals
Fairview Microwave Inc., a supplier of on-demand microwave and RF components, introduces a new family of broadband, high power limiters that aid in protecting sensitive RF receivers and components such as LNAs that are in close proximity to high power signals. The new high power limiters from Fairview Microwave operate over broad frequencies ranging from […]
Gallery: Cool circuits in evidence at the 2015 International Microwave Symposium
The International Microwave Symposium in Phoenix called itself the forum of choice for papers in the emerging RF and wireless growth areas. Judging by some of the technology on the exhibition floor, the event lived up to its advanced billing. Here are a few of the more notable developments we saw while walking the aisles. […]
Basics of RF switches
by Tim Galla, Product Manager, Active RF/Microwave Components, Pasternack Enterprises RF and microwave switches route signals through transmission paths with a high degree of efficiency. Four fundamental electrical parameters characterize how these switch designs perform. Several electrical parameters are associated with the performance of RF and microwave switch designs, but four are considered to be […]
Testing wireless devices for electromagnetic compatibility
by Nicholas Abbondante, Chief Engineer for EMC, Intertek Group Wireless devices must function in an increasingly hostile RF environment. Here are a few tips on setting up a test regime that can uncover problems. It is increasingly critical to test and evaluate wireless devices for electromagnetic interference (EMI) and to ensure they comply with electromagnetic […]
Cellular amps boost mobile and M2M applications
by Dermot O’shea, President, Taoglas Antenna Solutions Cellular signal amplifiers help bring reliable communications to remote locales, but there are subtleties to their deployment that can trip up the uninitiated. As we all know, cellular radio networks use base stations to cover a specific area. Rural areas have fewer base stations. So cellular coverage in […]
Analyzing millimeter frequencies with external harmonic mixing
by Cherisa Kmetovicz, Keysight Technologies (formerly Agilent Technologies electronic measurement business) External mixers can help extend the capabilities of signal analyzers so these instruments can handle frequencies ranging into several hundred gigahertz. Short-range connections are increasingly making use of millimeter-wave signals. Application examples include satellite-to-satellite links, point-to-point radios, secure communications, and wireless audio and video […]
How to sniff out EMC problems
by Alan Lowne, President, Saelig Co. Inc. It pays to do preliminary studies before sending products off to the test lab for electromagnetic compatibility problems. An engineer in a relatively small company usually must rely on experience and tribal knowledge to design a product that is electromagnetically compatible (EMC) with other equipment. Many designers and […]
