RF & WirelessComponents2015 Product SelectionGuideZ-Communications, Inc. is pleased toannounce the release of a new ProductSelection Guide. This short form catalogincludes a wide variety of surfacemount VCO (Voltage Controlled Oscillator)and (PLL) Phase Locked LoopSynthesizer modules ranging from40 MHz to 15 GHz.Users can download an electronic versionof the product guide in PDF orcontact the company for a hard copyversion. A complete listing of all availableparts and specifications can be foundon the company‘s web site.■ Z-Communications, Inc.www.zcomm.commance. And at 90 CoreMark/mA the SoCis up to 2X as power efficient as competingsolutions.Built on a cutting-edge 55 nm process, thenRF52832 includes 6x6 mm QFN and miniature3x3.2 mm CSP packaging options.The nRF52832 also includes a full rangeof on-chip analog and digital peripheralsfor glueless interfacing to external componentssuch as sensors, displays, touchcontrollers, LEDs, keypads, motors, digitalmicrophones, and audio Codecs. Thismakes it an ideal single-chip solution forwearables, human interface devices such asremote controllers, toys, smart home devicesand appliances, and wireless charging.■ Nordic Semiconductor ASAwww.nordicsemi.comHigh Linearity,Ultra Low Noise AmplifierRFMW, Ltd. announced design and salessupport for a high-linearity, active bias,ultra low noise amplifier from SkyworksSolutions. The SKY67103-396LF offersmid-band noise figure of 0.6 dB for receiverapplications requiring the lowest possiblenoise figure yet highly linear performanceover a broad frequency range.Covering 500 - 4000 MHz, the SKY67103-396LF provides typical OIP3 of 34 dBmat 3.6 GHz for improved receiver selectivityand sensitivity. RF power gain of16.5 dB extends receiver reception rangeand 17.4 dBm input compression level supportsa wide range of receiver input powerhandling. Targeting wireless infrastructuremacro base stations, small cells, DAS andremote radio heads, the SKY67103-396LFperforms in high temperature implementationsto 105 °C. The SKY67103-396LF isavailable in a 2 x 2 x 0.75 mm DFN package.■ RFMW, Ltd.info@rfmw.comwww.rfmw.comNew VCO: 1.8 GHz CRODesign in a CompactPackageZ-Communications, Inc. announced anew RoHS compliant VCO model. TheTRO1800A-LF is the first in a new line ofCeramic Resonator VCOs which saves preciousboard space while delivering exceptionalphase noise performance. This innovativeVCO covers the frequency of 1.8GHz within a tuning voltage range of 0.5to 4.5 V while featuring a spectrally cleansignal of -117 dBc/Hz @ 10 kHz offset.However, making the TRO1800A-LF evenmore attractive is its compact housing whichprovides nearly a 70% reduction in overallvolume size in comparison to other CROtopologies.The TRO1800A-LF is designed to deliver4 ±3 dBm of output power into a 50 ohmload while operating off a 5 V supply anddrawing typically 25 mA. This high performanceVCO operates over the extendedcommercial temperature range of -40 to +85ºC. The TRO1800A-LF features a typicalsecond harmonic suppression of -10 dBcand comes in Z-Comm‘s standard 375package measuring 0.375 x 0.375 x 0.12 in.It is available in tape and reel packaging forproduction requirements making it idealfor automated surface mount assembly andreflow. The TRO1800A-LF is well suitedfor microwave radio and satellite terminalapplications where space and noise performanceis a premium.■ Z-Communications, Inc.www.zcomm.comUltra Wideband DigitalAttenuatorRFMW, Ltd. announced design and salessupport for a 0.1- 31 GHz digital attenuatorfrom Qorvo. The TGL2223 offers 5-bit resolutionwith 0.5 dB least significant bit stepsize providing 15.5 dB overall attenuationrange. Ideal for use in Radar systems, electronicwarfare and communication systems,insertion loss of the TGL2223 ranges from1.8 to 4.2 dB. The Qorvo TGL2223 comesas a 1.18 x 0.8 mm chip.■ RFMW, Ltd.info@rfmw.com,www.rfmw.comhf-praxis 9/2015 71
