RF & Wireless News

RF & Wireless News Products AR Europe Welcomes Noisecom and Boonton as new Partners Wireless Telecom Group announced an agreement with AR Europe for the distribution of Boonton Electronics and Noisecom products throughout Europe. AR Europe‘s RF expertise and instrumentation experience along with their sales and distribution reach will place Boonton RF power meters, sensors, meters and analyzers along with Noisecom noise generation components, modules and instruments in front of design and test engineers, system integrators and field service technicians across Europe. Wireless Telecom Group is committed to working with AR Europe to provide the highest quality customer service, technical support and RF instrumentation solutions. „AR Europe‘s focus on both commercial and military aspects of communications, compliance, automotive and aerospace sectors are well aligned with our focus and our products,“ said Dan Monopoli, Wireless Telecom Group General Manager of Test and Measurement. „Their approach to relationship building and customer service, as well as the complementary nature of their current product portfolio will help us find new opportunities and growth across Europe.“ Mark Reeve, Director of Operations for AR Europe added, „We are very pleased to be appointed the European distribution partner for Wireless Telecom Group. The Boonton and Noisecom brands are well established, respected and recognized in the industry for offering a range of high quality, innovative products which are a perfect fit for us“. ■ AR Europe www.ar-europe.ie Waveguide Direct Read Attenuators Covering 18 to 110 GHz Pasternack has released a new line of waveguide direct read attenuators for instrumentation, test benches, high efficiency RF/Microwave transmissions, SATCOM, MILCOM, radar and telecom applications. Pasternack’s direct read attenuators are available in WR-42 to WR-10 waveguide standards operating in seven waveguide bands within the 18 GHz to 110 GHz frequency range. They boast ±2% typical attenuation accuracy and feature an easy-to-read drum scale and military standard UG-style flanges. Minimum attenuation range is 0 to 50 dB with an insertion loss of 0.5 to 1 dB depending on the frequency range. These direct read waveguide attenuators can be used in many industries including aerospace, defense, industrial, telecom, instrumentation and medical. They are built from quality construction materials and ensure consistent performance. Pasternack Inc. www.pasternack.com New Cable Filter RLC Electronics‘ Cable Filters can be designed as either lowpass, highpass or bandpass constructions, covering frequency ranges up to 50 GHz. These filters are available in conformable & semi-rigid cable styles that are built to your cutoff, rejection and mechanical specifications, including cable length, bend position and angle. The filter shown above is a 27 GHz lowpass filter, with rejection of 40 dB at 35 GHz, 65 dB at 43 GHz and 50 dB up to 50 GHz, while maintaining low loss (1 dB max, 0.8 dB typ.) over the passband. ■ RLC Electronics, Inc. www.rlcelectronics.com Tunable Cavity Filters RLC Electronics manufactures tunable cavity bandpass filters that feature sharp stop band rejection and lower losses than comparable tubular bandpass filters. Parallel coupled round rod distributed resonators afford small size and high Q to achieve a near ideal bandpass response. Units are constructed to operate over the most severe military environmental conditions. These filters offer a tuning range of ±7.5% (from center frequency). The unit pictured above is a filter that offers center frequency to be tunable/adjustable from 1025 to 1150 MHz, with the typical 3 dB bandwidth being approximately 5 MHz. ■ RLC Electronics, Inc. www.rlcelectronics.com High-Power Filters RLC Electronics‘ high-power lowpass filters are designed for high power systems in the frequency range of 100 to 8000 MHz. These filters are designed to handle 2500 watts average under extreme temperature and altitude conditions, while offering low loss (0.2 dB typ.) and 1.5 VSWR (max). RLC filters offer you the flexibility of choosing your cutoff frequency, number of sections and connector type (N, SC, HN, 7/16) for a truly custom high-power lowpass product. The unit shown is a 2500 MHz lowpass filter with SC connectors, designed to handle 500 watts CW into a 3:1 load. ■ RLC Electronics, Inc. www.rlcelectronics.com GaAs MMIC Fundamental Mixers Richardson RFPD, Inc. announced the availability and full design support capabilities for two GaAs MMIC fundamental mixers from Analog Devices, Inc. The HMC557A is a general-purpose, double balanced mixer in a 24-lead, ceramic 4 x 4 mm LCC package that can be used as an up-converter or down-converter from 2.5 to 7 GHz and requires no external compo- 64 hf-praxis 2/2017

RF & Wireless Products nents or matching circuitry. The HMC557A provides excellent local oscillator (LO) to radio frequency (RF) and LO to intermediate frequency (IF) isolation due to optimized balun structures. It is suitable for fixed wireless, point-to-point and point-tomultipoint radios, test equipment and sensors, and military end use applications. The HMC773A general-purpose, double balanced mixer, available in a 24-lead, ceramic 3 x 3 mm LCC package, can be used as an up-converter or down-converter from 6 to 26 GHz and also requires no external components or matching circuitry. Optimized balun structures result in excellent LO-to-RF and LO-to-IF suppression, and the mixer operates with LO drive levels above 13 dBm. The HMC773A is suitable for point-to-point and point-to multipoint radios and VSAT, test equipment and sensors, and military end use applications. ■ Richardson RFPD Inc. www.richardsonrfpd.com High-Power SMT Attenuators Richardson RFPD, Inc. announced the availability and full design support capabilities for a new series of high-power SMT attenuators from American Technical Ceramics Corp. (ATC). The AT0603 series provides virtually flat loss over a broad frequency spectrum and is ideal where low noise, low inductance and low parasitic capacitance is required. The film metallization provides stable characteristics over temperature and time, and balanced Pi design provides even current distribution and accurate attenuation characteristics from DC to 20 GHz. The attenuators are ideal for impedance matching, input padding and signallevel tuning. The AT0603 series is designed to meet a wide range of RF and microwave large- and smallsignal applications, including telecommunications, satellite communications, cellular base stations, microwave radio, ISM, RF and microwave power, military and aerospace, and test and measurement. ■ Richardson RFPD, Inc. www.richardsonrfpd.com 1000 V SiC MOSFET Richardson RFPD announced the availability and full design support capabilities for a new silicon carbide power MOSFET from Wolfspeed, a Cree Company. The 1000 V, 65 mOhms C3M0065100K is in an optimized four-lead TO-247-4 package with a separate driver source pin. This package provides lower switching losses with minimal gate circuit ringing due to the Kelvin gate connection. The package features a notch between the drain and source pins, which increases creepage distance to best support operation of higher voltage discrete devices. The new device is optimized for electricvehicle charging systems and three-phase industrial power supplies, and it addresses many power design challenges by providing a unique device with low on-Resistance, low output capacitance and low source inductance, for an ideal blend of low switching losses and low conduction losses. ■ Richardson RFPD, Inc. www.richardsonrfpd.com MMIC Power Doubler for DOCSIS 3.1 RFMW, Ltd. announced design and sales support for a high-linearity MMIC power doubler designed to support DOCSIS 3.1 CATV requirements. The Skyworks ACA1216 offers 27.5 dB typical gain at the upper end of its 50 to 1218 MHz frequency range. Ideal for hybrid fiber coax (HFC) equipment including line extenders, nodes, system amplifiers and headend equipment, the ACA1216 operates using 12 V and 725 mA. Control pins allow independent control of input and output stage currents. CTB is measured at 78 dB while Xmod is -66 dB and CSO is -70 dB. The SOIC16 wide-body package has a heat slug leaving plenty of margin for heat flux yet minimizing board space and external components. ■ RFMW Ltd. www.rfmw.com Low PIM Adapters MECA offers Low PIM (-165 dBc typ.)
