Skyworks Solutions enhances its Intera family of power amplifiers and front-end modules, adding a new high-power quad-band solution compatible with system-on-chip architectures designed for handsets in emerging markets. The new SKY77531, which is part of the company's InteraLite portfolio of solutions targeted at emerging markets, provides many of the same competitive advantages as the company's dual-band transmit and receive GSM/GPRS front-end module – small form factor. Integrating a power amplifier, PA controller and pHEMT switch, the front-end module leverages the company's advanced manufacturing techniques to reduce the RF footprint and overall bill-of-materials – two key challenges OEMs face when designing low-cost phones. In emerging markets, both consumers and operators require handsets that are inexpensive, yet meet or exceed specific requirements for size, quality, and reliability. Given its high-power efficiency, this solution also maintains overall thermal performance and improves battery life.

The SKY77531 is a high-power efficiency transmit and receive quad band 6 x 8 mm FEM with integrated power amplifier control that contains a quad-band gallium arsenide heterojunction bipolar PA, a 1P6T pseudomorphic high electron mobility transistor switch to enable flexible phone layout, and an integrated complementary metal-oxide semiconductor -based controller to manage the PA and switch. Its innovative architecture also maintains overall thermal performance and battery life. Designed in a low profile and compact form factor, the SKY77531 also offers a complete transceiver or SoC output-to-antenna and antenna-to-receive surface acoustic wave filter solution.
