2008 Test Systems Catalog

7/21/2008 12:51:25 PM

JFW offers a broad selection of custom integrated RF systems. We've designed and built test systems for applications as simple as a single programmable attenuator in a benchtop enclosure and as complex as a 48 x 96 matrix switch. JFW beats out the competition by offering you test systems that are custom designed for your application without charging any NREs. If you don't need a custom test system, JFW also has a wide selection of existing RF test systems to choose from.

Datasheet: YellowFin WiMAX Analyzer

7/8/2008 4:35:52 PM

YellowFinT WiMAX analyzer is the world's first truly portable calibrated, demodulating WiMAX test receiver. This handheld unit utilizes the Samsung Q1 Ultra tablet UMPC as an interface in conjunction with Berkeley's precision receiver technology for complete spectrum analysis as well as WiMAX packet demodulation. The receiver sweeps the 2.0 - 5.9 GHz spectrums to within +1.5 dB accuracy. YellowFinT performs full spectrum analysis allowing RF engineers to see the whole wireless network picture. Features include power triggers, peak hold/search, markers and multiple waveform traces. WiMAX packet analysis includes RSSI measurements for Cell-ID & segment, multipath analysis and CINR (Carrier-to-Interference-plus-Noise-Ratios) on a preamble basis. The optional DF (Direction Finding) Antenna allows engineers to pinpoint sources of WiMAX interference, rogue base stations and even nearby hackers. An internal 12-channel/satellite GPS receiver allows for geo-coded WiMAX site surveys and drive-studies using optional mapping software.

Application Note: RF/IF-To-Digital Connected Solutions Bit Error Rate Using The Advanced Design System

7/1/2008 4:32:00 AM

Designing and verifying designs to today's complex signal formats can present some interesting challenges. Designs can be verified in simulation and they can be verified after all of the hardware returns from fabrication - but an intermediate level of verification early in this design/fabrication cycle can be difficult to achieve due to the need for prototype hardware.
