Keysight Technologies Deutschland GmbH New RF Equalizers RLC Electronics‘ gain and line loss equalizers combine filter and attenuator technology to achieve a desired response to 40 GHz. The typical curves that follow are representative of commonly requested responses, including both linear and half-sine responses. SWR is dependent on frequency of operation, complexity of equalized response, and bandwidth of response. Power handling is dependent on the physical size of the absorptive elements. Since these elements decrease in size with increasing frequency, power handling by 10 GHz is usually in the hundredths of watts. The power capability of these devices is seldom an issue, since their usage is generally in receive stages or in the low power sections preceding transmit amplifiers. These units are used to compensate for such things as cable or system gain/losses, to gain flatness in amplifiers, and compensate for devices such as couplers and filters which have frequency dependent outputs and allow for compensation to ensure a flat response. ■ RLC Electronics, Inc. Absorptive Bessel Filters to 30 GHz RLC Electronics‘ 4th Order Absorptive Bessel Filters provide the excellent group delay response of Bessel filters while maintaining impedance matching far into the stop band. Resistive elements are designed into these filters, resulting in a response that closely mimics the classic Bessel in both amplitude and phase. These filters are used in digital systems where truthful reproduction of waveforms is important. These filters are now available with -3 dB cut off frequencies as high as 30 GHz. A surface mount configuration is available to 4 GHz. ■ RLC Electronics, Inc.

The wide frequency, 50 MHz to 8 GHz, and measurement, -40 dBm to +20 dBm, ranges provide high performance at a great price and ensures the ability to test a wide variety of cutting edge devices. The intuitive user interface and powerful programming tools provide easy access to all measurements as well as special features, such as multi-channel measurements, channel-to-channel math and strip chart recording. These product specifications and features position the CPS2000 as an ideal tool for high-volume manufacturing test. ■ Boonton/AR Wireless M-Bus Module with Integrated Sensor Interfaces Radiocrafts AS announced two new Wireless M-Bus modules, both with integrated sensor interfaces. The new modules are 66 hf-praxis 5/2018

RF & Wireless ideal for making Wireless Sensor Networks (WSN) or Low Power Wide Area Network (LPWAN) with wireless sensors. Meeting the demand for easy access to sensor data, the new modules rely on a proven, robust and widely deployed protocol, the Wireless M-Bus standard (EN 13757). The protocol is very power efficient and ideal for sensors with an operating lifetime of 10 - 20 years on a single cell battery. The 169 MHz narrowband solution is recently gaining a lot of market traction as it is an optimal solution for Industrial sensor networks, where reliability, robustness and security are of great importance. The RC1180-MSM operates at 868 MHz, and RC1701HP-MSM operates at 169 MHz, an expansion of the RC1180-MBUS3 and RC1701HP-MBUS4 industry proven modules. The new modules offer a dedicated interface for a number of industrial and environmental sensors, such as temperature, humidity and gas. The sensors are carefully selected to enable users to build complete sensor nodes by just adding the sensor, an antenna and a power supply to the compact MSM module. Sensor interfaces supported includes analogue inputs, GPIO, SPI and I 2 C. Wireless M-Bus is of particular interest for environmental sensors in buildings, at larger plants and as a part of a smart city IoT network, as the infrastructure often is already present due to utility meter reading systems. 868 MHz are widely used for reading household meters in Neighbourhood Area Networks (NAN), while 169 MHz with its much larger coverage due to the ultra-narrowband technology are used for gas and water meters in LPWAN networks. ■ Radiocrafts AS Power Shunt Up to 600 A The new HS series from KOA is ideal for sensing currents up to 600 A.
