RF & Wireless Components Guerrilla RF’s Newest Broadband, Ultra-Low Noise Amplifier LNA provides excellent linearity, flat gain and ultra-low NF for small cells and wireless infrastructure devices covering wide frequency range with a single match. Guerrilla RF Inc., introduced its latest Ultra-low noise amplifier (Ultra-LNA) with industryleading broadband RF performance for small cells, macro base stations, distributed antenna systems (DAS) and other wireless devices in the 700-2700 MHz band. According to Research and Markets, the overall wireless network infrastructure market will witness tremendous growth over the coming years. Growing at a compound annual growth rate of over 5 percent, the market will account for over 4 billion in annual spending by the end of 2020. The GRF2104 is a broadband Ultra-LNA designed for small cells and other high performance applications requiring a single device, which can support multiple frequency bands with a minimum of external components. Its flat 20 dB gain, along with outstanding NF and linearity over 700 - 2700 MHz, make it an ideal solution. Internal prematching to 50 ohms results in a compact, low-cost solution, while its flexible biasing offers high levels of reuse – within a design and across platforms. GRF2104 is offered in a thermally efficient 1.5 x 1.5 x 0.5 mm plastic package. ■ Guerrilla RF guerrilla-rf.com New Two-way microwave power divider Link Microtek has announced the availability of a new twoway power divider that is particularly suitable for use in military mobile jamming systems to counter the threat of IEDs. Manufactured by Narda Microwave, the Model 2382-2 power divider operates over microwave frequencies from 500 MHz to 6 GHz and can handle an input Products New Connectors for TFT-402 Low PIM Jumpers for DAS Applications Times Microwave Systems has introduced eight new factory installable connectors for TFT-402 jumpers. These high quality connectors attach via soldering of the center pin and induction soldering to the cable outer conductor and provide excellent VSWR performance and reliable PIM performance better than -155 dBc. TFT-402 is an ultra-flexible 0.160 inch power of up to 250 W CW or 2 kW peak. As well as functioning as a power divider, it can also be used as a combiner for very high power non-coherent signals. The device offers exceptional performance, with an insertion loss of no greater than 1.5 dB at any frequency in its range, a typical phase balance of ±7deg and a maximum amplitude balance of 0.4 dB. Maximum VSWR is typically 1.5:1 at all ports, and minimum isolation is specified as 9 dB at frequencies below 1 GHz and 17 dB above 1 GHz. Model 2382-2 has a microwave power handling capability of up to 100 W CW under any load condition, rising to 220 W CW for a load VSWR of 2:1 and 250 W CW for a load VSWR of 1.2:1. Featuring a rugged construction for excellent long-term reliability, the new power divider weighs just 396 g and has overall dimensions of only 88.9 x jumper cable meeting the requirements of UL 910 for plenum applications. TFT-402 jumper cables are suitable for in-building jumpers and interconnects up to 6.0 GHz and are UL listed and printed as well as 100% tested for static and dynamic PIM. New CCT-02 Cable Cutting Tool Available The new Times CCT-02 cable tool which replaces the older CCT-01 model is the perfect 63.5 x 25.4 mm, excluding the N-type female connectors. ■ Link Microtek sales@linkmicrotek.com www.linkmicrotek.com VCO Features Superior Phase Noise for Low Cost Basestation Systems Z-Communications, Inc. announced a new RoHS compliant VCO (Voltage Controlled Oscillator) model CRO2273B- LF. It operates at 2265 to 2280 MHz with a tuning voltage range of 0.5 to 4.5 VDC. This high performance VCO features a spectrally clean signal solution for cutting any LMR cable in preparation for connector termination. The CCT- 02 tool cuts more easily, provides a clean sharp cut without leaving any metal or plastic residue across the face of the dielectric and allows the cable to retain its shape without distorting its geometry thereby preventing any added return loss which may be of particular concern especially at higher frequencies. New features of the CCT-02 tool include a unique safety locking mechanism to keep the tool positively closed until needed or when stored in a pouch and a streamlined design that allows it to fit more easily into a Times or other type of tool pouch. ■ Times Microwave Systems www.timesmicrowave.com 58 hf-praxis 4/2015

RF & Wireless Components of -115 dBc/Hz @ 10 kHz offset and covers the band with a typical tuning sensitivity of 4 MHz/V. The CRO2273B-LF is designed to deliver +3 dBm of nominal output power into a 50 Ω load while operating off a 5 VDC supply and drawing typically 20 mA of current. This low noise VCO operates over the extended commercial temperature range of -40 to 85 ºC. The CRO2273B-LF features typical second harmonic suppression of -15 dBc and comes in Z-Comm’s standard, MINI-16-SM package measuring 0.5 in. x 0.5 in. x 0.22 in. It is available in tape and reel packaging for production requirements making it ideal for automated surface mount assembly and reflow. The CRO2273B-LF is well suited for microwave radio and basestation applications that require low phase noise performance. ■ Z-Communications, Inc. www.zcomm.com Products True DC to 8 GHz Switch Two-Stage Power Amp serves Small Cell Applications RFMW, Ltd. announced design and sales support for the industry’s first RF switch operating at zero Hertz with integrated RF, analog and digital functions.
