Homebrew SWR and power meter To begin with, this SWR meter featured in this article is not completely homemade, as I used the circuit design from the schematic in the highly regarded book Arduino Projects of Amateur Radio. Despite purchasing the book and honoring the authors’ copyright, I will still provide my own diagram here.

X-FAB Silicon Foundries SE, the leading analog/mixed-signal and specialty foundry today announced the availability of new high-voltage primitive devices targeted at the growing market for automotive 48V board net and battery management system (BMS) ICs. Covering voltages of 70V to 125V, these complementary NMOS/PMOS devices are based on the company’s XT018 BCD-on-SOI (https://www.xfab.com/en/technology/soi/018-um-xt018/) platform with deep trench isolation (DTI)
Ricoh Electronic Devices launched RP516 and RP517 series, buck (step-down) DC/DC converters featuring ultra-low output voltage (0.3 V to 1.2 V) and ultra-low quiescent current (typically 0.3 µA). The new converters are designed for IoT systems. As the IoT market expands, IoT devices with sensors, MCUs, communication ICs, etc. are required to correspond to low voltage to prolong the operating time of the

Diodes Incorporated announced the introduction of the AP43770 USB Type-C™ power delivery (PD) controller, a highly integrated solution for implementing PD over USB in fixed and portable devices, and offline power adapters. The AP43770 is well-suited to a range of applications where USB PD is implemented, including AC adapters, power hubs, battery banks, and USB PD converters. It features an embedded
As electronic devices become more advanced, the power supply voltage of LSIs used in them is lowered, so their power consumption can be reduced and their speed increased. However, a decrease in the power supply voltage also causes the requirements regarding voltage fluctuations to become more severe, creating a need for high-performance DC-DC converters to

Introduction Previously I made a simple frequency-modulated continuous-wave (FMCW) radar that was able to detect distance of a human sized object to 100 m. It worked, but as it was made with minimal budget and there was a lot of room for improvement. FMCW radar working principle If you have read my previous articles you
