Smyrna, Ga. Murata Electronics has announced the introduction of planar high-density passive device (PHPD), which the company calls a revolutionary technology that is ideal for low-height components. PHPD technology, which is realized by thin-film printing on high Q ceramics, can be applied to many components including filters, diplexers, baluns, couplers, impedance transformers, phase transformers, power combiners and dividers, directional power monitors, and mode transformers.
The first such component realized from PHPD, micro chip filters, benefit from this miniaturization and low loss component technology, making them the lowest height component in the world with this function measuring at 1.2 x 0.8 x 0.4-mm. The new micro-chip filter was designed to be the lowest cost filter for applications such as WLAN, UWB and RF-ID.
PHPD technology is ideal for makers of power amplifiers and other modules where low-height components are desired. Its miniaturized size will help enable the trend towards smaller and smaller wireless products.
"Murata is on the cutting edge in introducing this new technology breakthrough which offers the ability to combine many functions while keeping a low profile a major concern in the module industry," said Scott Klettke, group product manager for microwave components at Murata Electronics. "The microchip filter using PHPD technology fills a void in the availability of low height filtering for highly integrated modules."
Pricing is dependent on the number of poles and the required performance. PHPD products are currently under development, however, samples are available upon request.
