Skyworks launches SOI-based LTE Tx/Rx main/diversity antenna switches for smartphones and tablets

Skyworks Solutions Inc of Woburn, MA, USA (which manufactures high-reliability analog and mixed-signal semiconductors) has unveiled five new LTE Tx/Rx switches for smartphones and tablets.

The SKY13414-485LF, SKY13415-485LF, SKY13416-485LF, SKY13417-485LF and SKY13418-485LF main/diversity antenna switches cover single-pole 4-throw (SP4T) through single-pole 8-throw (SP8T), and allow up to eight bands of WCDMA/LTE.

The high linearity and low insertion loss achieved by the suite of devices suit switching applications commonly used in LTE-based handsets, data-cards and tablets. Their symmetric design and higher power handling also provide flexibility in signal routing for higher-power TD-SCDMA/TDD-LTE, WCDMA/FDD and LTE transmit/receive functions, says Skyworks. In addition, their good isolation and pin-to-pin compatibility, along with their high linearity, help with co-existence issues in smartphones and tablets, reckons the firm.

Because the devices are designed with a silicon-on-insulator (SOI) process featuring an integrated general-purpose input/output (GPIO) logic controller, no external blocking caps are required, notes Skyworks.

Samples are available. Pricing depends on quantities.
