PRODUCTS 39 RMS power detector targets WCDMA, WiMAX and LTE applications precisely measures signals with highly varying crest factors up to 6 GHz control, transmitter signal strength indication (TSSI) and RF instrumentation. Accurate control of PA output power signiﬁcantly reduces cost and improves efﬁciency. The AD8363 is ideally suited for nextgeneration RF applications using complex signals with highly varying peak-to-average ratios. The signal is sent directly into the single-ended input eliminating the need for an external balun, unlike power detectors from previous generations. The device achieves +0.5-dB accuracy over the entire 50-dB + 1-dB dynamic range. The output is linear-in-dB, and scaled to 50 mV/dB, but other slopes can be arranged. Fully speciﬁed and stable over the entire frequency range of 50-Hz to 6-GHz, the AD8363 has a operating temperature range of -40 to 125 degrees Celsius and supply voltage range of 4.5 to 5.5 V. With these speciﬁcations the most stringent power measurement applications can be accurately realized. www.mwee.com/206800283 VCOs ultra low phase noise VCOs, PLL Modules, Synthesizers, 100 MHz – 18 GHz, patented coupled resonator technology, ultra low phase noise standard and custom made The AD8363 TruPwr™ root-mean-square (RMS) power detector from Analog Devices precisely measures signals with highly varying crest factors up to 6 GHz used in WiMAX/802.16, WCDMA, TD-SCDMA, and LTE applications. The device supports the communications industry’s focus on increasing efﬁciency and improving ease-of-use to reduce the overall system size and cost. The AD8363 targets high performance RF applications including power ampliﬁer (PA) linearization/control loops, transmitter power FILTERS Custom speciﬁc ceramic ﬁlters, 300 MHz – 6 GHz Second source to most manufacturers Entry level microwave spectrum analyzer takes aim at WiMAX, WCDMA and other mobile applications The portable FSL18 18-GHz spectrum analyzer from Rohde & Schwarz expands the company’s product portfolio for spectrum analysis to meet the increasing demand for compact instruments in applications such as the installation and maintenance of WiMAX networks. The 18-GHz analyser claims to offer a unique combination of wide frequency range and large I/Q demodulation bandwidth (28 MHz) for an entrylevel class instrument. Featuring a frequency range of 9 kHz to 18 GHz, the FSL18 can perform measurements on microwave systems. This includes radar and microwave link systems as well as production tests on microwave components such as mixers and ampliﬁers. Due to its large I/Q demodulation bandwidth and the extensive software capabilities of the FSL family, the new spectrum analyzer claims to be the only instrument in its class to support the WLAN, WiMAX and WCDMA standards. The instrument’s low weight (under 8 kg) and DC/battery operation also make it ideal for mobile use in the ﬁeld when no AC supply is available. Transmitter measurements for civil and military applications — from WiMAX and Satcom up to radar — can be performed easily. When equipped with the FSL-K9 option, FSL analyzers support the direct connection of power sensors from the company’s NRP family. This GSM-GPRS MODEM Dual-band GPRS class 10 /class B engine Industrial grade –40 °C to +85 °C; ATEX ready Connectorized, Plug-In or SMD reﬂow modules T-Mobile qualiﬁcation pending ISM TRANSCEIVERS increases the accuracy of the measurements and eliminates the need for an extra power meter. An overall measurement uncertainty of less than 1.2 dB at 18 GHz ensures precise results, even in the microwave range. In addition, the instrument’s resolution bandwidths (RBW) from 1 Hz to 10 MHz (20 MHz at zero span) provide high ﬂexibility for analyzing pulse signals in both the frequency and time domains. For production applications, the FSL18 is a cost-efﬁcient solution with a wide range of functions. www.mwee.com/206800063 240 to 960MHz; suitable for narrow band Sensitivity: –117 dBm; data rate 1 to 128 kbps Antenna Diversity and Switch Control OOK-, FSK-, und GFSK-modulation +11 to +20 dBm TX Output Power 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.compotron.com sales@compotron.com ● Microwave Engineering ● March 2008 www.mwee.com 039_MWEE.indd Sec1:39 20/02/08 14:45:31 8010002 WWW.2PUNKT.DE http://www.mwee.com/206800283 http://www.compotron.com http://www.mwee.com/206800063 http://www.compotron.com http://www.mwee.com
