Avago Technologies has announced two new front end modules that incorporate a power amplifier, duplexer, band-pass filter and coupler to improve efficiency and extend talk time in mobile handsets. Avago’s AFEM-775x series includes Avago’s CoolPAM and Film Bulk Acoustic Resonator technologies to improve performance in CDMA cell band and dual-band handsets, wireless PDAs and wireless data cards.

To meet the needs of today’s radio and RF communication equipment designers, Analog Devices, Inc. (ADI) today introduced the ADL5324 half-Watt RF driver amplifier. When compared to other RF driver amplifiers, the ADL5324 offers superior power efficiency and temperature tolerance. The ADL5324 operates over a wide temperature range (-40°C to +105°C), and can be biased to operate on less power.

Analog Devices, Inc. today introduced an 11-bit D/A converter that enables cable television and broadband operators to synthesise the entire cable spectrum up to 1 GHz into a single RF port, while consuming a maximum of 1.1 W of power. The AD9737A 2.5-GSPS D/A converter’s wide bandwidth and dynamic range enable cable infrastructure designers to increase QAM (quadrature amplitude modulation) channel density by 20 times over present cable modem ...

Analog Devices released today new single- and dual-channel 14-bit high-speed A/D converters. With high speed and high accuracy, the compact, cost-effective and functionally flexible components are effective for use in communications, instrumentation and test and measurement applications.

3M, through its New Ventures Business, has invested in GoNano Technologies Inc., a developer and manufacturer of high surface area nanomaterials for pollution control, catalysis, composites and sensory technologies headquartered in Moscow, Idaho. Terms of the transaction were not disclosed.

Atmel LED driver family offers intelligent control for backlighting and solid state lighting markets; Combination of LED drivers with Atmel AVR and ARM-based MCUs offer optimal power efficiency, flexibility networking ability and lower BOM

Is your current LCD going end of life? Does the recommended replacement LCD have an LED backlight and a built-in driver? Are your current input signals incompatible with the new requirements? Would you like to make the LCD upgrade as seamless as possible? ERG’s Smart Bridge™ module resolves many of the problems users are currently experiencing – quickly, easily and economically – by using the system’s existing input power signals and co...

CUI Inc announced the addition of a new surface mount series to its high efficiency, constant current dc-dc LED driver family. Designed to drive high power LEDs, the VLD25-SMT series provides efficiency levels of up to 96%, current accuracy of ±2%, and an ultra-wide input range of 5.5 to 48 Vdc. The series offers two means of LED dimming: PWM digital dimming and analog dimming control via a trim pot, making it ideal for applications where prec...

HEP has launched a series of newly developed DC/DC Converters for LED lighting fixture. There are 12 models of boost converter available in 350mA or 700mA outputs, and 3 models of buck converter available in 350mA output. Also we offer customized and quick-to-market service.

Although it is relatively straightforward to design a basic LED driver for a general lighting application, it becomes far more complex when additional functionality such as phase cut dimming and power factor correction are also required. A non-dimming LED driver with no power factor correction generally consists of an off line switching power supply configured to regulate the output at a constant current. This is not much different from a standar...
