PRODUCTS 59 Spectrum analyser up to 7.5 GHz, hand-portable WiMAX band isolators and circulators cover 700 to 3600 MHz in standard industry sizes The latest addition to Raditek’s high-volume/lowcost range of isolators and circulators, the SS Series is a stripline drop-in model that covers 700 to 3600 MHz at 10 percent bandwidth with industry standard sizes. Capable of handling 110 W of reﬂected power these devices are ideal for WiMAX, cellular and PCS applications. www.raditek.com Willtek Communications has presented its 9103 Handheld Spectrum Analyzer operating at frequencies up to 7.5 GHz. The instrument supports many microwave applications, featuring all the typical measurements of standard desktop spectrum analyzers such as channel power, occupied bandwidth and adjacent channel power ratio. Additional measurements such as tracking generator-based cable measurements (distance to fault, voltage standing wave ratio), an RMS detector, radiation emission and RF pollution are achieved through options. VSWR and DTF measurements support antenna installation and veriﬁcation (optional), while a tracking generator option enables cable measurements in the ﬁeld. The spectrum analyser also meets outdoor requirements from technicians in the ﬁeld because the large display is easy to read even at bright daylight. Applications covered by the 9103 with the 7.5 GHz frequency extension include aviation signals, directional radio, VSAT (very small aperture terminal), and signals in the 5 GHz unlicensed band, such as Wireless LAN (WLAN) and WiMAX. RFID signals are best analyzed in the zero-span mode provided by the spectrum analyzer. Willtek’s 9103 also supports a wide range of applications with accessories for cable fault ﬁnding, EMC and radiation measurements and fault ﬁnding in 3G mobile phones. Displayed average noise level is -117 dBm, while dynamic range is 70 dB. www.willtek.com Microwave Engineering ● October 2007 ● www.mwee.com 059_MWEE.indd Sec1:59 21/09/07 11:05:19 http://www.raditek.com http://www.resistor.com http://www.willtek.com http://www.mwee.com
