Planning and designing an integrated wired/wireless network before construction begins pays big dividends later. By Ahmet Tuncay, Trapeze Networks and Paul Kish, Belden. click to enlarge Figure 1. Additional cabling from wiring closet switches to Wi-Fi mounting locations in ceilings should be accounted for in the initial cabling plan, leaving a 15- to 20-foot service loop at the end as wiggle room in case AP locations later require adjusting.
Fox Electronics recently introduced two new series of ceramic SMD (surface mount device) automotive-grade crystals built to operate at extended temperature ranges and engineered to withstand higher levels of shock and vibration. The FXA5032B and FXA7050B crystals are used in a variety of automotive timing applications, including GPS navigation, high-end audio and video systems, wireless phones, collision warning systems, Antilock Brake System controller, RADAR and onboard computer systems.
Crystek's CVCO55CC-3318-3467 VCO (Voltage Controlled Oscillator) operates from 3318 MHz to 3467 MHz with a control voltage range of 0.1 V~16 V.

Mini-Circuits’ PMA-545+ is a E-PHEMT based ultra-low noise MMIC amplifier operating from 100 MHz to 6 GHz with a unique combination of low noise and high IP3 making this amplifier appropriate for sensitive receiver applications. This design operates on a single 3 V supply and is internally matched to 50 Ohms.
Anritsu Company introduces the VectorStar Broadband ME7828A vector network analyzer system that produces industry-best dynamic range, measurement speed, and calibration and measurement stability over the broad frequency range of 70 kHz to 110 GHz. The performance and frequency coverage provide designers and manufacturers of microwave/millimeter wave components and devices with a single system to accurately and quickly measure devices from DC to daylight.
Texas Instruments Incorporated (TI) announces a new family of DSPs (digital signal processors) enabling residential and enterprise femtocell manufacturers and service providers to reduce development time and deliver new products to market quickly. TI’s family of multicore femtocell solutions includes a full portfolio of complementary analog solutions, support for Linux, and software solutions from TI third parties, Continuous Computing and mimoOn.
Renaissance announces the release of a 1.5 to 2.2 GHz quasi drop-in circulator with removable SMA connectors for a space application. This device was constructed to provide high isolation and low insertion loss over a wide operating temperature range while keeping in mind the importance of achieving proper grounding when mounting the device to ensure optimum performance.
Saelig Company, Inc. has released the CANminiBOX™, a versatile, compact embedded controller that is particularly well-suited for embedded CANbus control applications. Units incorporate high-reliability components, with a wide variety of hardware and software options also available in the tiny Élan-based CANminiBOX™.
Murata Power Solutions has introduced a new quad sampling Analog to Digital (A/D) converter for image processing applications where low noise performance and the ability to convert full-scale step input signals at a 10 MHz conversion rate is required. The ADSQ1410 is a functionally complete, quad 14-Bit resolution, 10 mega samples per second (MSPS) converter.
National Instruments has released the NI GPS Simulation Toolkit 1.5 for LabVIEW, an extension of the graphical system design environment that expands the NI RF PXI platform to provide engineers a cost-efficient, high-performance solution for GPS receiver testing that exceeds the capabilities of traditional box instruments.
National Instruments announces a new wireless local area network (WLAN) test solution that can generate and analyze RF signal measurements four times faster than other modular instrumentation solutions and up to 10 times faster than traditional box instruments. The test solution combines new NI WLAN Measurement Suite software for the National Instruments LabVIEW and LabWindows™/CVI development environments with NI 6.
Ramtron’s FM24CL32 is a serial nonvolatile RAM that offers high-speed read/write performance, low voltage operation, and impressive data retention. The FM24CL32 features 32-Kilobit (Kb) nonvolatile memory, 2.7- to 3.6-V operation in an 8-pin SOIC package that uses two-wire (I2C) protocol. The FM24CL32 features fast access, NoDelay™ writes, virtually unlimited read/write cycles (1E14), and low power consumption.
