Often a transmission line is buried, concealed behind finish surfaces, or otherwise not readily accessible. So it is difficult to locate faults by means of visual inspection. It is, however, feasible to locate such discontinuities via a test instrument known as the time domain reflectometer (TDR). The TDR is sometimes compared to a radar installation, […]

New 10-slot 3U development chassis for OpenVPX, SOSA designs
A new 10-slot 3U OpenVPX enclosure system is geared for SOSA (Sensor Open Standard Architecture) requirements. The new chassis platform features removable sidewalls, allowing the open frame enclosure to be optional fully enclosed. The 10-slot backplane has clocking and VITA 46.11 system management connections per SOSA requirements. It has multiple VITA 67.3c and VITA 67.3d […]
MOSFET relays switch high currents with low leakage
New non-leaded, high-current G3VM- WR MOSFET relays come in a P-SON package and handle load voltages of 30/60/100 V. The 30-V relay handles a continuous load current of 4.5 A max. The 60-V relay handles continuous load current of 3 A max. The 100-V relay handles continuous load current of 2 A max. The relays […]
Unlicensed spectrum use: What’s the technology behind it?
Unlicensed LTE lets wireless carriers offload traffic to Wi-Fi frequencies, but it must coexist with Wi-Fi and not interfere. Here’s how it works.
IoT: How 5G differs from LTE
5G extends its scope beyond consumer only to many new vertical and enterprise markets. Thanks to its flexibility and improved performance, 5G opens the door to many industrial applications. When researchers and engineers began developing 5G in 2012, they began to look at use cases. The primary motivation for launching a new generation of wireless…
Renesas adds three timing ICs for 4G/5G radios
The 8V19N850 radio synchronizer and 8V19N880/8V19N882 jitter attenuators enhance a radio unit’s timing capabilities.
Tiny, PMBus 1.3-compliant buck regulators offer output current up to 40 A
Vishay Intertechnology, Inc. broadened its offering of microBUCK synchronous buck regulators with a new family of 15 A, 25 A, and 40 A devices featuring input voltages from 4.5 V to 20 V in the thermally enhanced 5 mm by 7 mm PowerPAK MLP34-57 package. Delivering increased power density and transient response compared to previous-generation […]
Synchronous dc-dc converters boast super-wide input range, reduction in component count
The MAX17577 and MAX17578 from Maxim Integrated Products, Inc. are the industry’s smallest, highest-efficiency synchronous inverting DC-DC step-down converters. As Maxim’s first 60V inverting DC-DC converters with integrated level shifters, these devices save up to 72 percent of board space by reducing the component count by half while using 35 percent less energy than the closest competitive solutions. […]
