Maxim DC-DC Power Modules
Maxim released its MAXM17552, MAXM15064, MAXM17900 and MAXM17903 step-down DC-DC power modules, letting engineers designing applications in factory automation, medical and communications tap into four micro-system-level IC (uSLIC) modules. The modules feature a synchronous wide-input Himalaya buck regulator with built-in FETs, compensation and other functions with a shielded inductor.

Microchip Low Dropout Regulator
Microchip introduced a linear Low Dropout (LDO) regulator that extends battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs. With a low Iq of 250 nanoamps (nA) versus the approximately 1 uA operation of traditional devices, the MCP1811 LDO reduces quiescent current, allowing users to recharge or replace batteries less often.
The MCP1811 also provides faster load line and transient response when compared to other low Iq LDOs. Faster response times can accelerate wake-up speed in devices such as monitors or sensors that require immediate attention.

NI Transceiver for Prototyping and Testing Radar Systems
National Instruments (NI) unveiled the FPGA-enabled PXIe-5785 FlexRIO transceiver,which aims to shorten the design cycle for radar applications in aerospace and defense.The PXIe-5785 FlexRIO transceiver can sample directly at RF, which simplifies and lowers the cost of highchannel-count systems.
This is especially important when building systems such as fully active phased-array radars, in which beams are formed using hundreds or even thousands of antenna elements. Because FlexRIO modules are based on the PXI platform, users can integrate systems and synchronize modules more easily compared to custom designs or alternative form factors, such as VPX.

Pasternack Coaxial RF Probes with Pogo Pin Design
Pasternack expanded its line of RF coaxial probes into the 40 GHz operating frequency range for use in microwave components, high-speed communications and networking. The line now includes four models that provide 10 dB maximum return loss over the frequency range of DC-40 GHz. These probes are offered in GS and GSG configurations with a pitch of 800 or 1,500 microns and a 2.92mm interface.
The probes are gold-plated and have compliant pogo pin contacts that allow for a range of probing angles. They can be used by hand, with or without a probe positioner, and can be cable mounted or mounted with Pasternack’s multi-axis probe positioner.

RS Components IoT Sensor Development
RS Components launched the UrsaLeo Pi development kit, which combines the Silicon Labs Thunderboard 2 sensor module with a Raspberry Pi development board, UrsaLeo Pi. Trading only reduced debug support and restrictions on hardware re-use, it is suited for cost-conscious development in sectors such as Industry 4.0, automotive diagnostics and general data monitoring.
The Thunderboard 2 module, as featured in the UrsaLeo UltraLite kit, contains temperature, humidity, UV, ambient light, barometric pressure, indoor air quality and gas sensors, a 6-axis inertial sensor, digital microphone and Hall sensor.
