PLANO, USA: Diodes Inc. announced the release of the ZXRE250 and ZXRE252 programmable shunt regulators. These devices feature a very low minimum cathode current for regulation of only 40µA, enabling improved efficiency in a range of applications including power supplies for consumer electronics such as computers, set top boxes and LCD TVs.
With the same electrical specifications as the industry standard TL431 but with a 10x lower cathode current, the three terminal regulators offer excellent temperature stability and output current handling up to 100mA. The devices’ regulated output can be set to any voltage between 2.5V and 36V using a pair of external divider resistors.
The ZXRE250 is provided in a choice of SOT23 and SOT25 packages, while the ZXRE252 offers an alternative pinout in SOT23. The parts offer standard reference voltage tolerance options of 1% and 0.5%, with a wide operating temperature range of -40 to 125°C. The regulators can also be used as direct replacements for Zener diodes in applications requiring an improvement in Zener performance.

Avago expands family of world’s smallest RF amplifiers
SAN JOSE, USA & SINGAPORE: Avago Technologies announced additions to its family of the market’s smallest RF amplifiers. The new VMMK-3xxx amplifiers leverage Avago WaferCap chip scale packaging (CSP) technology to offer an ultra-small footprint of 1.0 by 0.5 by 0.25 mm. The amplifiers bring a host of new functionality to the existing Avago VMMK-1xxx and VMMK-2xxx families, including a positive gain slope low-noise amplifier (LNA), a wideband LNA, a variable gain amplifier (VGA), and four directional detectors.
With miniature 0402 package dimensions and no wirebonds, the VMMK-3xxx amplifiers experience almost no signal loss and minimal parasitics. The devices take up 5 percent of the volume and uses only 10 percent of the board area of solutions using a standard SOT-343 package. In some cases, the miniature amplifiers can effectively reduce PCB area by more than 50 percent.
The ultra-small package size and fully-matched surface mount design are optimized for 500 MHz to 12 GHz frequencies, making the high-performance devices ideal for a variety of radio architectures and space-constrained applications. The VMMK-3xxx LNAs and VGA can be used in UWB, WLAN, WiMAX, generic IF amp and gain block applications, while the new detectors can be used in base stations, point-to-point radios and generic power control loop detectors, as well as for monitoring power amplifier output.
The VMMK-3xxx family supports full surface mount capability, requiring no special tooling for assembly. The amplifiers have all I/Os routed to the backside of the device wafer through via-holes, resulting in RF transitions suffering almost no signal loss and minimal parasitics. This is a significant improvement over conventional plastic packages where bond-wires exhibit substantial parasitics that limit the operating frequency.
The miniature amplifier family provides high gain, a high third-order intercept point (IP3) for good linearity, low noise figure (NF) and integrated 50-ohm input and output matching networks to simplify system design.

Avago intros white HB LED in durable surface mount package for streamlined assembly
SAN JOSE, USA & SINGAPORE: Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, announced a white high-brightness LED in a robust surface-mount (SMT) package that simplifies manufacturing.
The new ASMT-UWB1 LEDs are available in a Plastic Leaded Chip Carrier (PLCC)-2 package encapsulated in a heat-resistant silicone resin, enabling them to operate in a wide range of environmental conditions with high reliability and long operating life.
The superior light output of the ASMT-UWB1 LEDs enables reduced component count to cut overall system costs. This high-brightness performance, along with a wide 120-degree viewing angle, makes the LEDs well-suited for illuminated advertising, backlighting of vending and gaming machines, as well as for office automation, electrical appliances and industrial equipment.
Designers are choosing surface-mount LEDs because of their ease of assembly, compact footprint, and manufacturing flexibility, which combine to reduce overall system development costs. The ASMT-UWB1 surface-mount LEDs are packed in EIA-compliant tape and reels for simplified pick and place assembly. Each reel is shipped from a single intensity and tight color bins following the ANSI C78.377-2008 color binning structure to provide better uniformity.
The LEDs also feature a low forward voltage value, with a maximum of 3.6V. This results in low power consumption for end-applications.
