System Designed to House Field Generation Equipment
The AS40006 AR System has been specially designed to house, in two, air-conditioned, EMI shielded equipment racks, the AR field generation equipment listed below. An additional control room rack cabinet of desk configuration is provided to house the field measurement and antenna height control equipment. This configuration provides a convenient tabletop location for the control … [Read more...]
New Energy Efficient RF Transistors Provide High-Reliable ESD Protection
Infineon Technologies has launched new RF transistors with electrostatic discharge protection for design of reliable, high sensitivity wireless communications devices. When used as the Low Noise Amplifier (LNA) stage of the RF signal chain, the new transistors reduce the risk of electrostatic discharge that can lead to failure or damage of the wireless system. The new energy … [Read more...]
Field Generation Test System Fully-Shielded To Prevent EMI Interference
AR RF/Microwave Instrumentation has designed a complete field generation test system that is fully shielded, making it ideal for use in an anechoic chamber without being susceptible to or causing interference.Model AS18013 houses a variety of field generation equipment in two air-conditioned EMI-shielded equipment racks. Among the included equipment is the SC1000M3 system … [Read more...]
Reporters Take Field Trip to an Apple Laboratory
A New York Times reporter in a recent tour of Apple’s EMC Laboratory described the company’s anechoic chamber and other features. The visiting press corps was led in and out of a series of specialized chambers, including one with a large antenna-studded arch that a tester can sit under to get a precise profile of the radio environment surrounding a human cellphone user.Read … [Read more...]
Engineers Test iPhone 4 Signal-Loss Problems
After testing three iPhone 4s in the controlled environment of a radiofrequency isolation chamber, Consumer Reports engineers confirmed that there is a problem with the iPhone 4’s reception. In the RF room, which is impervious to outside radio signals, the test engineers connected the phones to a base-station emulator, a device that simulates carrier cell towers. The engineers … [Read more...]
iPhone Antenna Design Absorbs EM Waves
Some of the reception problems with Apple’s iPhone 4 have been linked to the product’s antenna, which is an unusual design in that it circles the entire perimeter of the device. Phone makers typically try to place the antenna in places the user is less likely to touch in order to make a call. But with iPhone 4, unless you put a insulating cover around the antenna, the design … [Read more...]
Conical Horn Antennas Feature Frequency Range of 4-26.5 GHz
ETS-Lindgren announced the availability of its new Model 3163 series conical horns antennas with a frequency range of 4 GHz to 26.5 GHz. The high gain (over 16 dBi) antennas are designed for use as feeds in tapered anechoic chambers, as well as in applications requiring high gain and linear polarization. These high gain horns exhibit improved reflectivity levels in the quiet … [Read more...]
