Jennic, a manufacturer of innovative 32-bit wireless microcontrollers has demonstrated the capability of its JN5148 to perform multiple packet transmissions from 100µJ of energy harvested from an electro-mechanical switch. Jennic is the first wireless microcontroller vendor to show ZigBee communications are possible with such low energy consumption. The demonstrator shows how a single switch press is all that is required to enable the JN5148 to ...

To overcome the frustration people can feel when electronic products ‘freeze’ in mid-operation, a new smart-reset chip announced by STMicroelectronics allows the system to be restarted safely without removing the battery or finding a tool to push the reset button, usually hidden behind a hole in the casing.

Texas Instruments has introduced the TCA8418, a keypad scan device that can generate an interrupt output signal using a three-key combination such as CTRL-ALT-DEL, which frees up the processor from scanning the keypad for presses and releases, saving power and bandwidth.

Avago Technologies introduces the industry’s first ultra broadband traveling wave amplifier for high-speed digital communications applications that operate in the 30KHz to 80GHz frequency band. Avago’s AMMC-5025 amplifier provides 8 dB of small signal gain and excellent gain flatness of +/-0.7 dB along with better than 10 dB input and output return loss to provide superior performance which is ideal for use in Test and Measurement equipment,...

Adding to its range of tactical antenna products, Radiall now provides stubby GPS passive and active L1 band antennas. The passive EPL 09-13 and active EPL 09-14 antennas are enclosed in a miniature robust package requiring little space on crowded handheld equipment requiring GPS L1 band connectivity.

Fairchild Semiconductor offers designers of 3G smart phones, cell phones, set-top boxes, security cameras and notebooks a camera switch portfolio that solves compelling design challenges in these applications.

AVX Corporation has expanded its Zinc Oxide (ZnO) based varistor series to include an 18V-rated version that exhibits a low leakage current of 1µA maximum, which extends battery life in portable devices. The UltraGuard Series multilayer ceramic varistors feature non-linear, bi-directional voltage-current characteristics similar to back-to-back zener diodes with an EMC (electromagnetic compatibility) capacitor in parallel.

Vishay has announced what it says is the industry’s first high-performance multilayer ceramic chip antennas for mobile devices to cover the entire UHF band from 470 MHz to 860 MHz. Utilizing Vishay's unique materials and manufacturing technologies, the new Vishay Vitramon chip antennas comply with the MBRAI standard while maintaining small outlines of 35 mm by 5 mm by 1.2 mm for the VJ 3505, and 10.5 mm by 15.5 mm by 1.2 mm for the VJ 6040.
