PRODUCTS 35 Low phase noise RF reference source designed to simplify RF calibration and improve productivity Fluke Europe has announced the Fluke 9640A-LPN (low phase noise) RF Reference Source, a higher-performance synthesizer designed to simplify RF calibration and improve calibration lab productivity for even more demanding workload coverage. The 9640A-LPN Reference Source joins the company’s 9640A in delivering level precision, dynamic range and frequency capability in a single instrument. They can be used to calibrate a broad range of RF test equipment including spectrum analyzers, modulation meters and analyzers, RF power meters and sensors, measurement receivers, frequency counters and attenuators. The phase noise specification of the 9640A-LPN is designed around maintaining adequate calibration margin capable of verifying the most demanding spectrum analyzers, including the Agilent PSA series and Rohde & Schwarz FSU Series. Previous systems typically used two or more signal generators to cover close-in and far-out measurements, or simply didn’t have the necessary test accuracy ratio. Now calibration labs get the performance they need with a single Fluke 9640A-LPN. Designed to replace popular but now discontinued synthesizers, the 9640A matches or exceeds performance OCXO/TCXO N 45 SMD OCXO series, 10 to 32 MHz ± 30 ppb, -40 to +85 °C, 3.3 volt supply, low proﬁle SMD of the HP 3335A Synthesizer/ Level Generator, while the 9640A-LPN matches or exceeds the phase noise performance of the HP 8662A or HP 8663A synthesizers. Typical phase noise at 1 GHz for the 9640A is 10 kHz offset -122 dBc/Hz, 1 MHz offset -130 dBc/Hz. For the 9640A-LPN, it is 10 kHz offset -138 dBc/Hz, 1 MHz offset -152 dBc/Hz. The 9640A-LPN features integrated signal leveling and attenuation within its precision leveling head, eliminating the need for characterization using a separate power meter and step attenuators, which is time consuming and difficult to automate. The leveling head delivers signals directly to the unit under test (UUT), maintaining signal precision and noise immunity throughout a +24 dBm to -130 dBm dynamic range to minimize losses, noise, mismatch errors and to maintain the calibrated integrity of the signal. The 9640A comes with a 50 ohm leveling head and has an option to add a 75 ohm head, which extends the instrument’s capability to calibrate workload with 50 and 75 ohm inputs, a unique characteristic in modern signal sources. Designed to simplify calibration lab applications, the 9640A features dedicated function keys, contextsensitive softkeys and a bright color display. Users can set a level or frequency step size and deviate the output to match specified target values while displaying the calculated UUT error for calibration certificate documentation. The 9640A-LPN is supported by a range of common RF workload procedures within the company’s MET/CAL® Plus Calibration Measurement Software, allowing quick automation of the calibration process while simplifying the documentation requirements for quality standards and tracking assets. www.mwee.com/207401974 VCO Ultra low phase noise VCOs, PLL modules, Synthesizers, 100 MHz to 18 GHz, patented coupled resonator technology, ultra low phase noise standard and custom made ISOLATOR 80 MHz to 28 GHz, High-power-isolators, Microwave-isolators FILTER 10 MHz to 28 GHz, Air Cavity, Ceramic LC, SAW 300 MHz to 4 GHz, ceramic loaded also available Germany UK Poland Denmark +49 89 53 88 66 -0 +44 17 93 60 24 40 +48 889 282 545 +45 217 980 68 WWW.2PUNKT.DE 8010007 Temperature compensated crystal oscillators target applications such as GPS, WLAN, WiMAX, base stations and mobile phones Raltron Electronics has released its RTXY104 series of temperature compensated crystal oscillators (TCXOs) designed specifically for GPS applications. The TCXO is also suitable for other applications including mobile phones, smart phones, WLAN, WiMax and other base station applications. Available in a 3.2 x 2.5-mm package, the RTXY-104 series offers a frequency choice of between 12.8 MHz to 40.0 MHz at a frequency stability of ±0.5 ppm over its temperature range of -30 to +85 degrees Celsius. Input current is at 2.7 V at 1.5 mA with a typical low phase noise ratio of -130 dBc/Hz at 1 KHz offset. The TCXOs feature a voltage control option making it applicable for PLLs, and low-power consumption, making the part suitable for battery-powered applications. www.mwee.com/207402047 CompoTRON www.compotron.com sales@compotron.com ● Microwave Engineering ● May 2008 www.mwee.com http://www.mwee.com/207401974 http://www.compotron.com http://www.mwee.com/207402047 http://www.compotron.com http://www.mwee.com
