Band Reject Filter Eliminates AWS Interference at ENG-RO Sites
API Technologies Corp introduced the CMD719 band reject filter designed to eliminate Advanced Wireless Services interference of electronic news gathering receive only sites. The Band Reject Filter eliminates brute force overload interference of ENG-RO sites caused by AWS operators transmitting at 2110.6 to 2121.5 MHz, and its group delay does not degrade digital ENG … [Read more...]
EMI Suppression Filter Connectors
Lane Electronics’ LMHF filter connector series is a version of Weald’s established and successful MIL-C-26482 series 1 compliant LMH bayonet coupling circular connector and, as a result, is ideal for demanding applications requiring EMI suppression. The connectors are designed to eliminate the need for external filters which means reduced weight and less assembly time and … [Read more...]
Surface Acoustic Wave (SAW) Filters Standard
IEC 60862-2:2012 gives practical guidance on the use of SAW filters which are used in telecommunications, measuring equipment, radar systems and consumer products. IEC 60862-1 should be referred to for general information, standard values and test conditions. This part of IEC 60862 includes various kinds of filter configuration, of which the operating frequency range is from … [Read more...]
New Material Filters and Polarizes Terahertz Radiation
Researchers at IBM's TJ Watson Research Center announce a new material made from several layers of graphene is an effective shield for terahertz and microwave radiation, while letting visible light through. The researchers created thin films that can be engineered to absorb radiation in a specific band of the electromagnetic spectrum. Shields made of the material could be … [Read more...]
Common Mode Power Line Choke for Ultra-Slim Products
With the WE-CMBH series, Wurth Electronics now also offers a common mode power line choke in a horizontal version. With a profile height of only 22mm, the power line choke is ideal for slim housings. Due to low-capacitance winding technology, suppression over a wide band is now possible. This makes the WE-CMBH an excellent choice for interference suppression in the frequency … [Read more...]
High Current DC, Single and Three phase AC Filters
LCR Electronics, Inc. has released a new product line of high current DC, single and three phase AC filters. LCR’s high performance, dual stage AC and DC filters were designed with higher inductance common mode coils to reduce excessive common mode emissions generated by high power SCR’s (Silicone-Controlled Rectifiers), and meet the stringent attenuation requirements of … [Read more...]
Tantalum Capacitors Offer 33-°F Capacitance in 1206 Footprint
