While the Omaha Community Playhouse has consistently received reviewer accolades for its performances, it has received criticism for its production audio. Unfortunately, the Omaha Community Playhouse is situated in an area with a lot of RF (radio frequency) activity. An antenna farm nearby is used by the area’s broadcasters, which caused significant interference problems and … [Read more...]

Navy Online Posts Request for Quote for EMI Laboratory Upgrade
The U.S. Navy Electronic Commerce Online (NECO) has posted a request for quote for an EMI laboratory Amplifier upgrade to obtain an electric field capacity in the frequency range of 26.5 GHz to 40 GHz to extend an existing MIL-STD-461F, test method RS103 capability. The EMI Lab Frequency Upgrade system needs to produce electric field strength of at least 200 Volts/meter at a … [Read more...]
MILMEGA to Make Presentation with ETS-Lindgren
MILMEGA and ETS-Lindgren are co-presenting a topical talk on the challenges of achieving a uniform RF immunity test-field over the 1-6GHz frequency range. Presented by Tom Mullineaux (MILMEGA USA Sales Manager) and Dr. Vince Rodriguez (ETS-Lindgren Senior Principal Antenna Design Engineer), the latest in 3D EM software is used to explore potential solutions in achieving the … [Read more...]
ESD Protection Diodes Target Portable Device Applications
The new ESD11N and ESD11B are two new offerings based on ON Semiconductor’s proprietary ESD protection technology. The two chips’ reduced size and bidirectional single-line design provides design flexibility and ease of routing in a variety of space constrained applications. The ESDN11 is a 6-pF device that maintains less than 0.5-dB insertion loss up to 3 GHz, and its … [Read more...]
ESD Protection Diode for RF Antennas
The ESD0P2RF-02LS from Infineon Technologies is 0.62 mm x 0.32 mm with a height of 0.31 mm. It can be easily integrated into complete modules and front-end systems. Crafted to protect electronic consumer and communications devices from electrostatic discharge, it can reliably absorb discharges up to 20 kV, a figure that significantly exceeds the industry standard IEC 61000-4-4 … [Read more...]
