According to AWR, the new interface “enables an intelligent, … [Read more...]
Measurement of Passive Intermodulation in Antennas
From the International Electrotechnical Commission Webstore: “IEC 62037-6:2013(E) defines test fixtures and procedures recommended for measuring levels of passive intermodulation generated by antennas typically used in wireless communication systems. The purpose is to define qualification and acceptance test methods for antennas for use in low intermodulation (low IM) … [Read more...]
Are X2Y Capacitors as Effective as Advertised? Are they Easy to Design Around?
Editor’s note: This question was asked in response to Interference Technology’s recent webinar by Keith Armstrong. To view the webinar, click here. Question: Are X2Y capacitors as effective as advertised? Are they easy to design around? Answer: Well, like Questions 6 and 7 above, this question isn’t related to the subject of my webinar, but I still have some time left to … [Read more...]
U.S. Air Force Completes Testing of “Flying Wireless Router” Software Upgrade
The U.S. Air Force (USAF) has completed testing on a new software upgrade designed to provide airborne US military aircraft with wireless router capabilities, enabling “almost instantaneous” communication between groups of ground forces. According to the USAF, the Net-T software upgrade will be included in the LITENING and Sniper advanced targeting systems. The Net-T … [Read more...]
