pSemi Intros Free "sNp Viewer" Software

sNp Viewer Software by pSemi - RF CafeDave Watling , of pSemi, went me a note about the company's new "sNp Viewer" multiport s−parameter plotting software that is available for free downloading on the pSemi website. It is provided as an executable installation file that installs the Runtime Vee framework for the program. Look for the sNp Viewer icon to appear on your desktop (not in the Start menu) when installation is complete. You can drag the icon into the Start menu afterwards. My guess is this was an tool developed for internal use by the engineering staff and it turned out so well that they decided to make it available to everyone. The example screen shot at the right uses the pSemi* PE42430 UltraCMOS® SP3T Reflective RF Switch, which is a 4-port device with a .s4p data file extension. I wanted to use a device with more than just two ports. The plots would get really busy ...

Advanced MMICs Aid in Reducing Size and Power in Phased Array Radar Systems

Advanced MMICs Aid in Reducing Size and Power in Phased Array Radar Systems - RF CafeCustom MMIC, a leading designer and manufacturer of high performance monolithic microwave integrated circuits (MMICs), has posted a new blog entry entitled, "Advanced MMICs Aid in Reducing Size and Power in Phased Array Radar Systems." Phased-array radar systems are important instruments in national electronic defense strategies. From the large, ship-based systems that scan for distantly launched missiles to the more compact arrays installed on fighter aircraft and unmanned aerial vehicles (UAVs), electronic phased-array radars come in many sizes and forms, providing reliable signal detection and identification. These modern systems offer many advantages over earlier radar ...

Investigating Inverters as Part of a Solar Array

Investigating Inverters as Part of a Solar Array - RF CafeAxiom Test Equipment, an electronic test equipment rentals and sales company headquartered in North County San Diego, has published a blog post entitled, "Investigating Inverters as Part of a Solar Array," which discusses the technical and test requirements for the subject. Solar power supplies are being used for remote and/or unmanned communications and data collection and reporting locations across the globe, and careful attention must be paid to component selection. RF Cafe visitor Joe Cahak published a great whitepaper entitled, "Solace in Solar," that provides a detailed look at his personal solar power installation project. Sophisticated test equipment is required ...

Temperature Chamber Choices

Temperature Chamber Choices (TotalTemp Technologies) - RF CafeJohn Booher, at TotalTemp Technologies has posted a blog entitled, "Temperature Chamber Choices." Thermal testing testing of products can't be ignored. Knowing your product stands up to the harshest environments it will be exposed to over the life of the product provides proof of the design and verified quality. With TotalTemp's Temperature Chambers and Thermal Platforms you can most effectively run thermal tests for burn-in or design / production verification. Products meant for consumers have to be tested, but it's safe to say, products going into space need far more rigorous verification. Life tests or inappropriate tests can go too far, thus shortening the life so it is important to ensure the proper testing is performed ...

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
