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 850MHz RX, 900MHz RX, 1.8GHz RX, 1.9GHz RX, 2.1GHz RX and 2.4GHz RX. Based on standard diversity platforms, these light-weight omni-directional radiation antennas feature low profiles and compact sizes. Sizes are 10-by-3.2-by-2 mm (width, length, height) and 310mg for the 1.8-, 1.9- and 2.1GHz antennas, 10-by-3.2-by-4mm and 600mg for the 850MHz and 900MHz, and 3.2-by-1.6-by-1.1mm and 33mg for the 2.4GHz 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 Pb-free, surface-mount processes. All products are field tested to ensure quality and reliability. Antennas are available in tape-and-reel packaging.
