28 PRODUCTS Miniature ferrite beads save space in EMI filtering applications To keep up with the industry’s demands for miniaturisation, Murata claims to have introduced the smallest ferrite beads available. Designed for EMI filter applications in DC power lines, these components will help to reduce board space without compromising on performance. The latest addition to the EMIFIL family of chip ferrite beads, the BLM02 series is available in the tiny 01005 size (0.4- by 0.2- by 0.2-mm). They are capable of wide frequency range attenuation, typically 30 MHz to several hundred MHz. Impedance ranges from 10 to 120 Ohms, with rated currents between 200 and 500 mA. DC resistance is below 0.8 Ohms for the whole series. Other additions to the EMIFIL family include the BLM03A, BLM03B and BLM03P series of chip ferrite beads in 0201 packaging. BLM03A ferrite beads feature CW signal generator line targets low-phase-noise applications AnaPico has released the APSIN3000 low-noise CW signal generator line. The frequency range covered with a 0.001 Hz resolution is from 9 kHz up to 3.3 GHz. An extended frequency version is also available with frequency coverage to 6.2 GHz (APSIN6000). RF power is settable from -50 to +13 dBm (>17 dBm below 2 GHz, optional -95 dBm to +20 dBm). The APSIN signal generators provide optimum signal purity with phase noise as low as -125 dBc/Hz at 1 GHz and 20 kHz offset) and low harmonic levels (typically 45 dBc). They are being touted as an alternative to expensive high-end RF signal generators. The APSIN3000 performs simultaneous frequency and power switching in less than 2 ms. Extensive frequency and power sweep capabilities (linear, log, random, programmable) make the signal generator well-suited for test applications. Selected modulation capabilities (FM, PM, fast pulse modulation) complete the feature set. www.mwee.com/208403071 a high impedance line up of between 10 and 1000 Ohms. Rated currents are 100 to 500 mA, while DC resistance is 2.5 Ohms maximum. The BLM03B series is available with impedances between 10 and 240 Ohms and features low DC resistance of between 0.4 and 1.5 Ohms. The BLM03P series features high rated currents up to 900 mA. All these components are all available with an operating temperature range of -55 to +125 degrees Celsius. www.mwee.com/208802730 Handheld real-time spectrum analyzers provides a live RF view of the spectrum Tektronix has introduced the SA2600 handheld real-time spectrum analyzer with DPX waveform image processor technology that provides a live RF view of the spectrum. DPX is now also available for the H600 “RF Hawk” handheld unit originally introduced in February. With these additions, Tektronix offers a full portfolio of real-time spectrum analyzers with DPX for use in the ﬁeld and the design bench. DPX waveform image processor technology in the SA2600/H600 displays the live spectrum by processing >2,500 or >10,000 spectrum measurements per second respectively. This is orders of magnitude more information than is shown by any other conventional spectrum analyzer without DPX, minimizing the analysis gaps inherent in swept spectrum and vector signal analyzers, Tektronix said. In addition to live RF, the waveform image processor also provides an intensity-graded persistence display that holds anomalies until the eye can see them to show the history of occurrence for dynamic signals and immediate feedback on signal variations over time. The SA2600, with 10-kHz to 6.2-GHz frequency coverage, 20-MHz real-time bandwidth and -153 dBm displayed average noise level (DANL), is designed to deliver benchtop spectrum analyzer performance in a battery-operated, handheld ﬁeld unit. With a spectrum processing rate more than 100 times faster than any swept spectrum analyzer from other vendors, the SA2600 and H600 provide 100 percent probability of intercept for transients with minimum event durations of 500 microseconds on the SA2600 and 125 microseconds on the H600, according to Tektronix. Designed for ﬁeld measurements, both models combine a high-performance spectrum analyzer with an intuitive set of user controls, enabling quick and simple classiﬁcation and location of both analog and digital RF transmissions. www.mwee.com/208802735 1-GHz RF tuner circuits in small package ensure clear video in CATV, DVR, PC TV Anadigics has launched the AIT1032, a fully integrated, 1-GHz tuner that enables crystal-clear video in CATV set-top boxes, DVRs, PC TV tuner cards, and other tuneron-board applications. Incorporating the upconverter, downconverter, VCO, synthesizer, RF and IF ampliﬁer, and RF and IF gain control functions into a single package, the device provides the low noise and low distortion performance required for high video quality in today’s CATV systems that combine digital and analog channel lineups together using a densely loaded spectrum. The AIT1032 provides two 45 MHz IF outputs, one for analog signals and one for digital signals. The digital output offers 78 dB (typical) conversion gain, with an adjustable IF ampliﬁer stage having 45 dB of gain control range. The analog output provides 65 dB conversion gain via a ﬁxed IF output ampliﬁer. The single RF input to the device contains a low noise ampliﬁer with 35 dB of gain control range. The device includes on-chip oscillator tank circuits that reduce component count and eliminate the need for any post-assembly manual adjustments. The tuner is optimized to avoid interference in MoCA-enabled applications. It operates from a single +5 V supply. www.mwee.com/208802734 Microwave Engineering Europe ● July/August 2008 ● www.mwee.com http://www.mwee.com/208403071 http://www.mwee.com/208802730 http://www.mwee.com/208802734 http://www.mwee.com/208802735 http://www.mwee.com
