Avago Launches Fully Integrated Broadband Miniature Variable Attenuator Module for Wireless Infrastructure Applications
Avago has announced a new fully matched wideband variable attenuator module for use in a wide range of broadband system applications. The ALM-38140, which is a 50MHz to 4 GHz PIN diode attenuator module, is a fully integrated solution that uses Avago's low distortion silicon PIN diodes housed in a miniature 3.8 mm by 3.8 mm by 1.0 mm multiple-chip-on board (MCOB) package with 6-pin configuration pads. This module is ideal for use wireless infrast...
New High Power Diode Ideal for Laser Projectors
The new high power laser diode PL TB450 from Osram Opto Semiconductors is mounted in a compact TO-56 package and features an optical power of 1.4 Watts (W), making it particularly suitable for high-quality professional projectors such as those used in offices, conference rooms and home cinemas. The latest in Osram’s portfolio of lasers on indium-gallium-nitride substrates, the PL TB450 is also excellent for a range of other applications from la...
Dynamic Backlighting Improves Contrast Ratio and Trims Power for Small LCD Panels
The perceived contrast ratio of a cell phone LCD display can be improved by using dynamic LED backlighting for enhanced video viewing. This application note describes how to add instantaneous pulse-width modulation (PWM) intensity control to an existing LED driver, using the MAX6948B as an example.
Intersil Introduces Ultra-Low Lux Digital Ambient Light Sensor
Intersil Corporation today announced the release of an ultra-low lux ambient light sensor, the ISL29033. With linear sensitivity down to 0.0019 lux, the ISL29033 is ideal for very low light applications such as light sensing behind dark glass and industrial design-challenging applications where typical light sensors have insufficient sensitivity (i.e. indirect light applications).
