Skyworks Solutions Inc of Woburn, MA, USA (which manufactures analog and mixed-signal semiconductors) has introduced a family of GPIO-controlled, high-performance RF cellular switches for LTE and GSM applications. The SKY13581-676LF single-pole, double-throw (SP2T), SKY13582-676LF single-pole, triple-throw (SP3T) and SKY13626-685LF single-pole, four-throw (SP4T) are for LTE, while the SKY13597-684LF (SP4T) is for GSM.
The new family of switches is suitable for smartphones, data cards and MiFi hotspot applications. The devices are designed to operate over the complete cellular frequency range including support for Band 42 and Band 43 (up to 3.8GHz), allowing the use of one part for all band requirements. They also feature low insertion loss for higher transmission efficiency and what is claimed to be excellent harmonic performance with improved receiver sensitivity.
The SKY13581-676LF, SKY13582-676LF and SKY13626-685LF share a common layout and are pin-to-pin, footprint compatible, enabling faster development time.
