Ethertronics Launches Actively Tuned DVB-H and FM Antennas
(Product News, 3 Jul 2008)
Ethertronics Inc. has released two new internal DVB-H and FM antennas designed to power an array of advanced industrial designs, mobile handsets and video products. Both the DVB-H and FM antenna solutions are engineered to address the challenges associated with incorporating multiple RF functions into portable devices. The products are parts of Ethertronics' new Tavvel line of actively tuned embedded antennas, which provide significant link budget improvements while maintaining a simple interface, compact size, and low current consumption.
Designed to operate on the entire DVB-H range of frequencies, from 474MHz to 870MHz, Ethertronics' tunable DVB-H antenna has been optimized to deliver average efficiency of 40 percent with current consumption of less than 100µA with a compact footprint of 50x13x1mm. In addition, the antenna element can be implemented in a variety of device form factors and requires a simple DC control voltage between 0 to 2.8V to tune the antenna to a specific frequency (channel) within the DVB-H band.
The new Tavvel embedded active FM antenna solution is ideal for integration into handheld devices, cellular phones, PDAs, laptops and other devices. Measuring 1cm³, the tunable antenna operates at the frequency range of 87.5MHz to 108MHz, ensuring maximum performance at every FM channel in the band. Performance is within 1dB to 1.5dB as compared to traditional headset lead-wire antennas. The FM antenna solution's current consumption is only 2.8mA, and tunes to specific frequencies (channels) by varying an input DC control voltage between 0 to 2.7V.
