Offered as a 5 x 6.65 mm chip, theTGA2239 is also available in a bolt-downpackage as the TGA2239-CP. Applicationsinclude Radar, data links and satellite communications.■ RFMW, Ltd.info@rfmw.comwww.rfmw.comNew Cable FilterRLC Electronics‘ Cable Filters can be designedas either lowpass, highpass or bandpassconstructions, covering frequencyranges up to 50 GHz.These filters areavailable in conformable (FCLPF Series)& semi-rigid cable styles (CLPF Series)that are built to your cutoff, rejection andmechanical specifications, including cablelength, bend position and angle. Computerdesigned and advanced coaxial techniquesensure optimal performance in a minimumamount of space.■ RFMW, Ltd.info@rfmw.comwww.rfmw.comOption Speeds Low-Frequency Impedance TestingKeysight Technologies, Inc. introduced anenhanced measurement speed option forits E4990A impedance analyzer. With thenew option, the low-frequency models ofthe E4990A are now as fast as the flagship120-MHz E4990A model.During inspection, manufacturers may haveto measure many devices in a day. Or, toaccurately evaluate devices like resonatorsor inductors, they may have to measuremany points per device. These tasks areall the more challenging when those measurementsare performed in impedance atlow frequency.Keysight’s new enhanced measurementspeed option addresses these challengesby allowing manufacturers to realize fastsweep speeds at low frequency using theaffordable E4990A impedance analyzer.They can use the option with the 10 MHz(Opt. 010), 20 MHz (Opt. 020), 30 MHz(Opt. 030) or 50 MHz (Opt. 050) low-frequencyoptions to the E4990A analyzer toenable a measurement speed improvementthat’s up to 10 times faster than what’s currentlyavailable on the market today.Keysight’s E4990A impedance analyzer isdesigned for R&D, quality assurance, productionand inspection engineers characterizingand evaluating passive electroniccomponents, semiconductor devices andmaterials. The analyzer has a frequencyrange of 20 Hz to 10/20/30/50/120 MHzand provides an industry best 0.045 percent(typical) basic accuracy over a wideimpedance range, with a 40-V built-in DCbias source. An equivalent circuit analysisfunction supports seven different multiparametermodels and enables engineers tosimulate their own equivalent componentparameter values.■ Keysight Technologies Inc.www.keysight.comAntennasAn Ultra Compact,Dual-Band Wi-FiAntennaAntenova, Ltd. is announcing a new,ultra compact, dual-band antenna for theWi-Fi 802.11n and ac 2.4 - 2.5 GHz and4.9 - 5.9 GHz bands. This new antenna,which is called Mutica, is designed tofit within a reduced ground plane onthe host PCB, making it ideal for thesmaller Wi-Fi products and wirelessaccessories being created today.Mutica is an SMD mounted antennafor all dual-band Wi-Fi applications,especially those requiring high speeddata transfer and multiple-in multipleout(MIMO) applications, for examplesecurity cameras, video cameras, settop-boxesand devices for connectedvehicles.Its specifications will also suit Wi-Fiaccess points, portable electronics,headsets, PC cards, games consoles,network devices and wearable electronics.Antenova takes a unique approach tothe design of its antennas, which itcalls “Design For Integration” (DFI).Because the antennas are always embeddedwithin a customer’s product,Antenova designs them so that theRF elements can easily be added tothe customer’s design, and so that theantenna will provide excellent performancewhen it is placed in positionon the PCB.Antenova gives advice on RF designand the integration of the antenna, alongwith engineering assistance and customersupport, and provides the CADfootprint files of each antenna free ofcharge to customers.The Mutica antenna is the first in thenew family of lamiiANT FR4 SMDantennas which Antenova announcedearlier this year.■ Antenova, Inc.www.antenova-m2m.comhf-praxis 9/2015 73
