Package Technology Shrinks RF Power Amp

Compared with existing approaches to RF integration, Pyxis offers to cut packaging costs in half while lowering package height 60% and reducing footprint by 75%. The first implementation of Pyxis will be a power-amplifier module that integrates triband GSM and GPRS amplifier die with surrounding passives (See the figure).

Compared with a laminate packaging technology employing discrete passives, which occupies a 90-mm2 footprint, the Pyxis implementation requires just 23 mm2 of board space. Future implementations of Pyxis will address the need to integrate RF transceivers, filters, and switches.
