WiFi 5GHz Front-End Module

Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, announced a highly efficient front-end module for WiFi access points. The new AFEM-S105 module integrates a power amplifier, directional coupler, and SPDT antenna switch in a small-footprint 3.2 by 3.2 by 0.6 mm package. The power amplifier is optimized for IEEE 802.11 a/n WiFi modulation, helping the module streamline design of mobile and fixed wireless data...

LED Backlight Driver with 2PWM Inputs

The AS3674 is an inductive highly efficient DCDC boost converter. The DCDC converter operates at a fixed frequency of 2MHz and includes soft startup to allow easy integration into noise sensitive RF systems.

A predictable startup is guaranteed even with very low duty cycle PWM input signals. The voltage on the output capacitor is controlled to minimize ripple and to avoid any acoustic effects for low frequency PWM input signals. The output of the DCDC converter is used for five current...

Full USB-Compliance Battery Charger

The bq24153A/6A/8/9 is a compact, flexible, high-efficiency, USB-friendly switch-mode charge management device for single-cell Li-ion and Li-polymer batteries used in a wide range of portable applications. The charge parameters can be programmed through an I2C interface. The IC integrates a synchronous PWM controller, power MOSFETs, input current sensing, high-accuracy current and voltage regulation, and charge termination, into a small WCSP package.

The IC charges the battery in three...

Small 3G and 4G Dual-Band Amplifier

TriQuint Semiconductor, Inc, a leading RF solutions supplier and technology innovator, unveiled the industry’s smallest dual-band PA duplexer (PAD) for global 3G and 4G smartphones. The new TRITIUM Duo™ family combines two band-specific power amplifiers (PAs) and duplexers in a single compact module, effectively replacing up to twelve discrete components.

“We’ve powered the world’s top smartphones with over a half billion of our single-band TRITIUM™ modules, and now the TRITIUM...

Mobile Smart Reset™ Chips

STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications and a leading manufacturer of standard ICs, introduced a new generation of its Smart Reset™ chips. Pioneered by ST who has already supplied tens of millions to major consumer-electronics brands, smart-reset Integrated Circuits provide a safe, convenient and intuitive means of resetting ‘frozen’ gadgets, such as mobile phones, media players, and other portable consumer...
