San Diego, Calif. Pulse, a Technitrol Company, has developed a line of high-performance ceramic diversity antennas. These antennas enable high-data-rate transmission, yet are small enough to fit in mobile terminals such as new-generation multimedia phones, notebook computers, PDAs, media players, WLAN routers, data cards, and other wireless devices.
The series consists of six products: the 850 MHz RX, 900 MHz RX, 1.8 GHz RX, 1.9 GHz RX, 2.1 GHz RX, and 2.4 GHz RX. Based on standard diversity platforms, these light-weight omni-directional radiation antennas feature low profiles and compact sizes. Sizes are 10 x 3.2 x 2 mm (width, length, height) and 310 milligrams (mg) for the 1.8, 1.9, and 2.1 GHz antennas, 10 x 3.2 x 4 mm and 600 mg for the 850 and 900 MHz, and 3.2 x 1.6 x 1.1 mm and 33 mg for the 2.4 GHz antennas.
Their ceramic composition provides a high degree of signal immunity, enabling them to be placed close to other antennas for high-performance diversity operation in small devices, said the company. Used in close proximity enables them to be switched within microseconds if one antenna experiences noise, providing improved signal quality with fewer drop-outs.
The diversity antennas are RoHS compliant and are compatible with lead-free, surface-mount processes. All products are field tested to ensure quality and reliability. Antennas are available in tape-and-reel packaging.
Availability: Delivery is six to eight weeks.
