World’s smallest ceramic NB-IoT antenna covers three global bands
The first two antennas in the Extensis range of narrowband IoT (NB-IoT) antennas include the world’s smallest ceramic NB-IoT antenna that covers Bands 5, 8 and 20 simultaneously with a single matching configuration. The antennas are specifically designed for NB-IoT solutions. The low-profile, highly efficient NCP.5820 is a NB-IoT ceramic surface mount multiband antenna that […]
Small antennas make possible cellular IoT wearable items
Altair Semiconductor and Ethertronics (a subsidiary of AVX) today announced a new small antenna technology, which will be demonstrated within a new cellular IoT wearable concept at Mobile World Congress Americas. The technology is a significant breakthrough that combines Ethertronics’ ultra-small antenna with Altair’s ALT1250 dual-mode Cat-M1/NB-IoT chipset algorithms to reduce the size of cellular wearable devices without […]
Filters suppress noise from 600 MHz to 2.7 GHz on audio lines
TDK Corporation has expanded the MAF1005G series of noise suppression filters for audio lines with four new MAF1005GAD-D types, which, thanks to their low DC resistance, feature a high rated current of up to 1.25 A. The new types employ TDK’s proprietary low-distortion ferrite that enables the new components to suppress noise at cellular frequencies from […]
Single-chip drivers for low- to mid-power motor control designs
Simplifying the design of low-to-mid-power motor controls in the 7V-45V range, the STSPIN830 and STSPIN840 single-chip drivers from STMicroelectronics contain flexible control logic and low-RDS(ON) power switches for industrial applications, medical technology, and home appliances. The STSPIN830 for driving 3-phase brushless DC motors has a mode-setting pin that lets users control the three half bridges […]
Direct drive ultrasonic ICs detect obstacles up to four meters
