Taoglas USA, Inc. a provider of antenna solutions to the M2M and connected device market, has teamed up with Peregrine Semiconductor Corporation to bring a dynamically tunable LTE antenna solution to the M2M market. The solution contains an embedded surface mount ceramic PIFA antenna from Taoglas—the Warrior PA.710.A—and Peregrine’s successful PE64102 DuNE™ Digitally Tunable Capacitor (DTC) on one evaluation board. It enables M2M devices to reach wide bandwidths and meet requirements for high performance using similar antenna space requirements as 3G/4G systems. Additionally, it has the ability to dynamically change the antenna band “on the fly” to match the cellular band a radio module is using. This new solution can be immediately tested via Taoglas’ DTAD.01 evaluation board, which will be unveiled May 21st at CTIA in Las Vegas at booth #5534. “This system will benefit our customers because it means they can achieve very high performance and throughput on those challenging lower frequencies such as 700 MHz, without dramatically increasing the size of the antenna,” said Ruben Cuadras, engineering manager with Taoglas USA. “Our Digitally Tunable Antenna (DTA)—the Warrior PA.710.A—helps customers reduce the size of their product and enables them to ‘re-tune’ an antenna whenever it is impacted by items such as a battery, enclosure or LCD. The antenna frequency can adjust for each specific location in cases such as when driving a car across multiple locations, or when a device moves between different countries. Teaming up with a top-tier company such as Peregrine means that, together, we can help our clients globally prepare their devices for LTE.” “Today’s wireless devices must now support a subset of more than 40 frequency bands, worldwide. M2M devices, in particular, must adapt ‘in the field,’ in order to connect to the strongest signal,” said Mark Schrepferman, director of the communications and industrial product line for Peregrine’s High-Performance Solutions business unit. “By dynamically tuning the antenna with DuNE DTCs, the system can support multiple bands while providing optimal RF performance. We are pleased to work with Taoglas to bring this cost-effective solution to the M2M market.” The evaluation board will be available directly from Taoglas and online in the coming months through its distributors. The Warrior PA.710.A wide-band antenna covers all working frequencies in the 3G/4G cellular space but will require a certain ground plane size.

Linear Technology has introduced a wireless charging receiver which has been optimized for low power applications. The LTC4123 combines a 30mW wireless receiver with a constant current/constantvoltage linear charger for NiMH batteries, such as Varta’s power one ACCU plus series. An external resonant LC tank connected to the chip enables the IC to receive power wirelessly from an alternating magnetic field generated by a transmit coil. Integrated power management circuitry converts the coupled AC current into the DC current required to charge the battery.The LTC4123 can be used for Wireless charging of a completely sealed product and eliminates the need to constantly replace primary batteries. ZnAir (ZincAir) detection allows applications to work interchangeably with both rechargeable NiMH batteries and primary ZnAir batteries with the same application circuit. Both battery types can directly power a hearing aid ASIC without the need for additional voltage conversion. By contrast, a 3.7V Liion battery requires a stepdown regulator in addition to the LTC4123’s functionality to power the ASIC.The LTC4123 rectifies AC power from the receive coil, and can also accept a 2.2V to 5V input to power a full featured constantcurrent/constantvoltage battery charger. Features of the charger include programmable charge current up to 25mA, a singlecell 1.5V battery charge voltage with ±0.5% accuracy, charge status indication and an on-board safety charge termination timer. A temperaturecompensated charge voltage protects the NiMH battery and prevents overcharging. The LTC4123 prevents charging when batteries are inserted with reverse polarity and pauses charging if the temperature becomes too hot or too cold. The receiver is housed in a highly compact, low profile (0.75mm) 6pin 2mm x 2mm DFN package with backside metal pad for excellent thermal performance. The device is guaranteed for operation from 20°C to 85°C in E grade. It is available for $2.65 each in quantities of 1,000 piece pricing starts at $2.65 each.

Small antenna technologies company, Pharad, has introduced a new antenna based on its Peel & Stick Appliqué antenna technology for Unmanned Ariel Systems and Drones. The design of the new L, S and C-band antenna has been optimized for Mobile Ad Hoc Networking (MANET) radios operating in both licensed and unlicensed Military, Federal, Broadcast Auxiliary Service (BAS), and Commercial bands.Pharad’s L, S, and C-band Peel & Stick Appliqué antenna offers an electromagnetically efficient radiating solution for a variety of applications, including UAV datalinks and covert vehicle communications. The portfolio provides a high quality radiating solution, while still being nearly as thin as a piece of paper (less than 10 mils thick) and also very lightweight; weighing less than 1 oz. A durable one-time use pressure sensitive adhesive on one side of the radiator allows the Pharad Peel & Stick Appliqué antenna to adhere to the surface. The application process takes only seconds to complete.The reduction in size and weight of UASs incorporating MANET radio modules, according to Pharad President Austin Farnham, has significantly decreased the space and weight allocation for antennas, but has not mitigated the need for high quality radiating solutions. In fact, UAS system integrators have demanded that the antenna solutions improve the range and persistence of the UAS platform. Extending the mission capabilities of UASs was the design goal in creating this new antenna. Pharad customers have found that the Appliqué antennas provide high performance radiating solutions while introducing virtually no aerodynamic impairment to the UAS flight profile.Pharad’s Peel & Stick Appliqué antennas for mini-UAV and drone applications are made in the USA and operate over the frequency ranges of 30 MHz to 10 GHz. The Appliqué antennas are suitable for non-carbon fiber composite UAVs such as those constructed of fiberglass, Kevlar, or polypropylene; common materials for small UAVs.
