The SKY18108-11 is a Single Pole, Nine-Throw (SP9T) antenna switch Front-End Module (FEM) designed for dual-mode, high power band switching applications that require low harmonics and low insertion loss. The device is optimized for both GSM/EDGE and TD-SCDMA systems. The SKY18108-11 consists of an SP9T switch, GSM transmit signal low-pass harmonic filters, and a GPIO controller. The low current consumption makes this device very suitable for battery operated applications. The SKY18108-11 is manufactured in a compact, 3.2 x 2.5 mm, 20-pin Multi-Chip Module (MCM) package.
