Introduction Insertion loss, the term used to express a filter’s ability to reduce or attenuate unwanted signals, has traditionally been measured in a 50 ohm source and 50 ohm load impedance condition, as standardized in MIL-STD-220. In this matched 50 ohm impedance condition, various types of filter circuit configurations, single capacitor, “L’s”, “PI’s”, and “T’s”, will … [Read more...]
EMP/HEMP Filter Meets Mil-STD-188-125, E1 & E2 Pulse Test Requirements
API Technologies’ model 52-1700-XXX High-altitude Electromagnetic Pulse (HEMP) Filters are designed to protect sensitive electronics equipment during hazardous transient conditions. They are employed to absorb a potentially destructive overshoot voltage. Under normal operating conditions, the suppressor circuit exhibits high off state impedance that appears transparent to … [Read more...]
More Applications Added to Popular Selective Radiation Meter
Narda Safety Test Solutions has added the LTE-TDD option to the latest generation of its highly specialized SRM-3006 Selective Radiation Meter. This puts the finishing touch to this frequency-selective handheld field strength measuring system, which has long been the benchmark device for rapid, reliable, standard-compliant safety assessments. The code-selective measurement … [Read more...]
New Solid State Broadband E-field Sources Introduced
AR recently introduced a set of new solid state broadband E-field sources with integrated horn antennas designed to replace traveling wave tube (TWT) amplifiers for immunity testing. The new E-filed sources are controlled by a master controller. There are two frequency ranges; 18 to 26.5 GHz and 26.5 to 40 GHz. Two field levels are available; 20 V/m and 50 V/m (both measured at … [Read more...]
Simulating EM Shielding for Aeronautical Applications
The airframe of an aircraft can provide some measure of shielding against high-intensity radiated fields (HIRF), but this is compromised by doors, windows, seams, access panels and components interfaced to the airframe such as antennas used for communication and navigation. Composite materials are increasingly used in aeronautical applications due to their relatively light … [Read more...]
New Scalable Power Amplifier with Simplified Test Setup
Empower RF Systems developed this industry first scalable architecture - their demonstrations of our broadband, high power 1KW 1 to 3 GHz amplifier - as way to supply a large variety of output power levels to many different customers and applications, but with only one fundamental design effort from our engineering group. The benefit to you is reducing your lifetime capital … [Read more...]
New Line of Flat Wire Inductors Introduced
ITG Electronics, a leading manufacturer of inductors and transformers in business since 1963, now offers a range common footprints as well as custom flat wire inductors for high power density and high frequency switching. As the name suggests, flat wire inductors utilize a flattened, rectangular cross section, copper wire instead of a traditional, circular cross section, … [Read more...]
Input Filters – The Key to Successful EMC Validation
Co-authored by: Ranjith Bramanpalli & Steffen Schulze Würth Elektronik INTRODUCTION Input filters are today as ever a requisite factor for successful EMC validation of switching controllers, irrespective of the size of the AC component involved. Switching controllers create conducted EMC interferences due to AC components in their lines, independent of their individual … [Read more...]
