productroundup GPS module integrates patch antenna Distributor MSC Technologies is stocking the L80 module from Quectel, an ultra-compact POT GPS module measuring 16 x 16 x 6.45mm including the integrated patch antenna. Based on the MTK3339 platform from Mediatek it supports 66 acquisition and 22 tracking channels. The module draws 20 mA in tracking mode, and has input sensitivity of -165 dB in tracking mode and -148 dBm in acquisition mode. It is suited for industrial applications due to its working temperature of -40 to +85 °C. EA SY Assisted GPS technology enables a first rapid localisation and high positioning accuracy even at indoor signal level. Satellite data can be automatically calculated with the ephemeris data from the past 3 days, which are stored in internal flash memory. In order to achieve an optimal balance between positioning accuracy and energy consumption, the ON-/OFF-Time can also be adjusted adaptively by Always Locate Complete article, here technology. 50-Ω 20dB to 2 GHz gain block LTC6431-20 is a 20 MHz to 2 GHz single-ended input and output fixed gain amplifier offering 46.2 dBm OIP3 (Output Third Order Intercept) and 2.6 dB noise figure. Its OP1dB (Output 1 dB Compression Point) is 22 dBm. Two grades are offered, an A-grade version that is 100% tested and guaranteed to have a minimum of 42.2 dBm OIP3 at 240 MHz, and the B-grade version offering a typical OIP3 of 45.7 dBm at the same frequency. Both input and output are internally 50Ω matched from 20 MHz to 1.4 GHz, with a frequency response of 20 dB power gain and a flatness of better than 0.5 dB. Internal 50Ω matching simplifies design and enables easy cascading, using minimum external components. Each amplifier needs only an input and output DC blocking capacitor, plus a choke to bias its open collector output. Complete article, here MIMO-capable wireless prototyping platform An integrated software defined radio solution for rapidly prototyping high-performance, multichannel wireless communication systems, the NI USRP RIO platform is built on the NI LabVIEW RIO architecture and combines a high-performance 2 x 2 multiple input, multiple output (MIMO) RF transceiver capable of transmitting and receiving signals from 50 MHz to 6 GHz with an open LabVIEW programmable FPGA architecture. Wireless engineers can use this technology to rapidly prototype real-time wireless communications systems and test them under real-world conditions. They can also more rapidly prototype increased-capability wireless algorithms and systems, and reduce time to results using what NI terms the only complete platform to take full advantage of a graphical system design approach. The USRP RIO family delivers high-performance, real-time processing capability with the Xilinx Kintex-7 Series FPGA. Complete article, here Broadband vector network analyser covers 70 kHz to 145 GHz Anritsu’s VectorStar ME7838D broadband system provides frequency coverage of 70 kHz to 145 GHz in a single sweep using a coaxial test port. The VectorStar ME7838D can conduct a single sweep on a device over multiple RF, microwave, and millimeter wave (mm-wave) waveguide bands, allowing engineers to more accurately characterise devices. The key enabler for broadband operation to 145 GHz is the Anritsu-developed MA25300A Non-Linear Transmission Line (NLTL) module, that extends the frequency range of previous Anritsu NLTL modules and is compatible with the basic VectorStar ME7838 system. Dynamic range of the VectorStar ME7838D broadband system is 120 dB at 10 MHz, 110 dB at 67 GHz, 109 dB at 110 GHz and 94 dB at 145 GHz. Stability is 0.1 dB over 24 hours; throughput is further improved by the instrument’s measurement speed of 110 msec for 401 points at 10 kHz IFBW.
