Abracon announces ASMPH family of compact multi-layer chip inductors for power applications

AUSTIN, TX. (19 January 2017) Abracon, LLC. (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components announces the ASMPH family of miniature multilayer power inductors for use in small form factor or battery powered solutions. The compact size, high self-resonant frequency (SRF)  and high efficiency, makes these inductors ideal for DC/DC conversion in space limited designs, including IoT and wearables. Standard operating temperature of -40°C to 85°C and robust construction is ideally suited for industrial applications. Constructed using low loss ferrite material, these inductors support high-speed switching frequencies used in power supply controllers in advance-miniaturized applications.

This family of power inductors offers multiple footprints and inductance tradeoffs. The space saving ASMPH-0603 footprint is 1.6×0.8×0.8mm with current ratings from 1250mA to 300mA and inductance values from  0.22µH to 2.2µH. With inductance values up to 4.7µH, the ASMPH-0805, ASMPH-0806 and ASMPH-1008 offer current carrying capabilities up to 1500mA, enabling a wide range of DC/DC power supply applications.

“Small form factor solutions benefit from the use of DC/DC power conversion,” comments Syed Raza, VP of Engineering with Abracon. “Switch mode, unlike linear power supplies, can remain efficient while operating over a wide input-to-output voltage conversion range, extending battery life. This family of miniature inductors from Abracon are instrumental in miniaturizing these designs.”

“These inductors hit the sweet spot of size, inductance, current carrying capability and maximum DC resistance enabling miniaturization.” states Juan Conchas, Director of Marketing for Abracon. “In conjunction with Abracon’s other product lines, these inductors address Abracon’s strategy of providing solutions across multiple technologies for growing applications such as IoT and wearables.”

Other applications for this series of product include medical monitoring, portable instrumentation, drones, robotics, battery powered equipment,  asset tracking devices, wireless connectivity modules and power supply modules.

Abracon Pierce Analyzer System (PAS) validates quartz crystals in-circuit

PAS-BC1WK/ PAS-BC2WK/ PAS-BC3WK

(Austin, TX) Abracon, LLC (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components announces the availability of an advanced proprietary Pierce analyzer system that validates quartz crystal performance in-circuit. The ability to sustain oscillation for a given quartz crystal oscillator design depends heavily on crystal’s motional parameters, board parasitics and oscillator circuit characteristics. The oscillator circuit is a closed loop system that sustains oscillation at an operating frequency, depending on the crystal plating capacitance (CL), crystal equivalent series resistance (ESR) and Oscillator Amplifier’s gain & phase response. Lower CL and lower ESR at the crystal level, enables the circuit to operate with adequate gain margin and improves the closed-loop stability; ensuring sustained oscillations across all variables, including variation in bias, loading, temperature and over time. Integrated circuits that use external quartz crystals do not always account for these key limiting factors. For instance, estimating or simulating the effect of board parasitics is not always possible. In-circuit testing of the quartz crystal while connected to the oscillator IC and attached to the board reveals design errors and inaccuracies that may cause over-drive, under-drive or center frequency deviations; or even the ability to sustain oscillations.

“Overdrive on the crystal causes long term reliability concerns due to microfractures within the crystal lattice. Under-drive may lead to complete oscillator loop failure, and center frequency errors as high as +/-500 parts per million may be completely out of range of acceptable frequency drift for a given application,” says Syed Raza, VP of Engineering with Abracon. “To conserve power, next generation IC’s must lower the gain in the oscillator loop requiring quartz crystals with much lower ESR at lower plating load. With next generation ultra-low power circuits used in the Internet of Things (IoT) and wearables, fabricated in <14 nanometer geometry; it’s no longer safe to assume that the oscillator will operate with sufficient gain margin, especially over temperature and time.

“The quartz crystal oscillator,” says Juan Conchas, Director of Marketing with Abracon, “sets the beat of the entire system. As oscillators are starved of power, failure to operate or operation off-center frequency is much more likely and more challenging to correct. For this reason, the ability to verify the performance of the crystal oscillator loop in-circuit, has become a necessary step in validating the overall system design.”

The service provides a comprehensive report outlining the functional parameters of the oscillator circuit and recommends changes when necessary. This service is conducted by Abracon and can be ordered through any franchised distributor, with multiple turn-around times from 2-week to 4-weeks.

PRESS RELEASE: Abracon Announces Compact Chip Antenna Solutions for Wearables and IoT

Abracon Announces Compact Chip Antenna Solutions for Wearables and IoT ACA-102, ACA-103, AMCA31

AUSTIN, Tx. (November 8, 2016) Abracon Holdings, LLC. (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components announces multiple compact chip antenna solutions targeting the main RF communications protocols widely necessary by the Internet of Things, the Industrial Internet of Things (IIoT) and  wearables product sectors. This series of chip antennas are designed to simplify critical trade-offs between size and RF power gain, an important factor in optimizing IoT and wearables functionality and design. Rugged ceramic construction supporting -40C to 85C operating temperature range ideally suits them for the demanding requirements of industrial applications.

The ACA-102 offers the most compact size supporting 2.4GHz Bluetooth, Bluetooth Low Energy (BLE) and WiFi/Wireless LAN applications with a small 2.0×1.2 footprint and 1mm height while offering -3dBi of gain.

The ACA-103 features dual-band  supporting Bluetooth/BLE/WiFi/WLAN at 2.4GHz with -4dBi of gain and WiFi/WLAN at 5.5GHz with -6dBi of gain in a compact  5.0×2.0x1.2mm form factor.

The AMCA31 offers the best gain in the series supporting  2.4GHz Bluetooth, Bluetooth Low Energy (BLE) and WiFi/Wireless LAN applications with a small 3.2×1.6 footprint and 1.2mm height while offering -1dBi of gain maximizing range and optimizing efficiency.

To further optimize end system design, Abracon offers antenna tuning services that measure gain and center frequency of the end system and confirm in-circuit performance of the antenna. In cases when the antenna is de-tuned due to non-optimal layout, ground plane or other issues, Abracon will recommend the optimal values to use on the pi-network matching the impedance between the RF IC and the antenna.

“Knowing that there is no free lunch when it comes to RF performance and size trade-offs, these antennas enable engineers to make appropriate decisions when designing their end systems,” says Dean Clark. “The IoT requires the use of small and efficient antenna solutions. The antenna efficiency is a major factor in maintaining end system communication range while keeping the power consumption as low as possible. The antenna selection and optimization is critical in this role.

Abracon offers a wide selection of antenna options. These solutions are available and in stock at Abracon’s major distributors world-wide.

“Due to a broad development of wireless applications in IoT, IIoT and wearables, the need for compact antenna solutions is growing explosively,” says Keith Chapman. “ Abracon is meeting that need by introducing advanced RF solutions and working closely with its global distribution partners to meet the go to market requirements of system designers.”
