  • Radio Frequency Interference Analysis of Spectra from the Big Blade Antenna at the LWDA Site
    Radio Frequency Interference Analysis of Spectra from the Big Blade Antenna at the LWDA Site Robert Duffin (GMU/NRL) and Paul S. Ray (NRL) March 23, 2007 Introduction The LWA analog receiver will be required to amplify and digitize RF signals over the full bandwidth of at least 20–80 MHz. This frequency range is populated with a number of strong sources of radio frequency interference (RFI), including several TV stations, HF broadcast transmissions, ham radio, and is adjacent to the FM band. Although filtering can be used to attenuate signals outside the band, the receiver must be designed with sufficient linearity and dynamic range to observe cosmic sources in the unoccupied regions between the, typically narrowband, RFI signals. A receiver of insufficient linearity will generate inter-modulation products at frequencies in the observing bands that will make it difficult or impossible to accomplish the science objectives. On the other hand, over-designing the receiver is undesirable because any excess cost or power usage will be multiplied by the 26,000 channels in the full design and may make the project unfeasible. Since the sky background is low level and broadband, the linearity requirements primarily depend on the RFI signals presented to the receiver. Consequently, a detailed study of the RFI environment at candidate LWA sites is essential. Often RFI surveys are done using antennas optimized for RFI detection such as discone antennas. However, such data are of limited usefulness for setting the receiver requirements because what is relevant is what signals are passed to the receiver when it is connected to the actual LWA antenna.

Gregory Kozlowski, Ph.D. Thesis Director Lok C. Lew Yan Voon, Ph.D. Chair, Department of Physics Committee on Final Examination Gary Farlow, Ph.D. Jerry Clark, Ph.D. Andrew Hsu, Ph.D. Dean, Graduate School Z. Jagoo Jagoo, Mohammud Zafrullah. M.S., Department of Physics, Wright State University, 2012. Radio-Frequency Heating of Magnetic Nanopar- ticles. Abstract In the present study, a power supply capable of converting a direct current into an alternating current was built. The frequency of oscillation of the output current could be varied from 174.8 kHz to 726.0 kHz by setting a set of capacitors in resonance. To this power supply is attached a 20-turns copper coil in the shape of a spiral. Because of the high heat generated in the coil, the latter has to be permanently water-cooled. A vacuum pump removes the air between the sample holder and the coil. A fiber optic temperature sensor with an accuracy of 0.001 ◦C was used to measure the temperature of the nanoparticles. Four ferromagnetic nanoparticles (CoFe2O4, NiFe2O4, Ni0.5Zn0.5Fe2O4, Co0.4Ni0.4Zn0.2Fe2O4) with different magnetic properties were subjected to heat- ing.

While it is true that RF increases the effort and cost of bringing a product to market, it also can add significantly to the function and salability of a completed product. Thanks to a growing number of easily applied radio frequency (RF) devices such as those offered by Linx, manufacturers are now able to quickly and reliably add wireless functionality to their products. The issue of legal compliance for the finished product is straightforward when approached in logical steps. Purpose of this Application Note This application note gives a brief overview of the legal issues governing the manufacture and sale of RF products intended for unlicensed operation in the United States under CFR 47 Part 15. In the United States the Federal Communications Commission (FCC) is responsible for the regulation of all RF devices. The FCC requires any device that radiates RF energy to be tested for compliance with FCC rules. These rules are contained in the Code of Federal Regulations (CFR), Title 47.

  • AMI Radio Frequency Frequently Asked Questions
    AMI Radio Frequency Frequently Asked Questions Q: Are there any health hazards associated with the new technology? A: No. The equipment operates at a low-power radio frequency, comparable to a cordless telephone. All equipment operates in compliance with state and federal communication standards. Water meters are typically installed away from the house so potential exposure is very limited; the communication device only turns on for a fraction of a second per day (totaling approximately 2 ½ minutes per year). Q: Do the AMI communication devices meet Federal Communications Commission (FCC) Radio Frequency (RF) limits? A: Like all commercially available telecommunication equipment, the AMI communication devices are required to meet Federal Communications Commission (FCC) Radio Frequency (RF) limits. Equipment manufacturers have vigorously tested and reviewed independent lab results demonstrating that the communication devices meet or exceed FCC limits. Common household items like cell phones, microwave ovens, baby monitors, cordless telephones and Wi-Fi routers emit much more radio frequency energy than AMI meters. Q: What is the frequency range for the radio communication devices? A: The meter communication devices and the network communication system will operate in the 450 to 470 megahertz (MHz) bands. The technology products the City will use for its Advanced Metering Infrastructure project comply with U.S. Federal Communications Commission (FCC) guidelines for human exposure to RF energy (FCC OET bulletin 65). Q: What are the key factors that contribute to RF Exposure from a communication device? A: There are three key factors that contribute to RF exposure: Signal duration: The communication devices connected to the water meters will normally transmit a signal for a fraction of a second per day or for a total of less than two minutes per year.

For this purpose a unique baseband signal which is common to the satellite-broadcasting system and the terrestrial distribution network is desirable; f) that the requirements as regards sensitivity to interference of the systems that can be used were defined by Appendix 30 of the Radio Regulations (RR); g) that complete compatibility with existing receivers is in any event not possible for frequency-modulated satellite broadcasting transmissions; ____________________ * Note – The following Reports of the ITU-R were considered in relation with this Recommendation: ITU- R BT.624-4, ITU-R BO.632-4, ITU-R BS.795-3, ITU-R BT.802-3, ITU-R BO.953-2, ITU-R BO.954-2, ITU-R BO.1073-1, ITU-R BO.1074-1 and ITU-R BO.1228.
