0.4-2.7 GHz SP9T Antenna Switch Module With GSM Transmit Filters

The SKY18120-11 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 GSM/EDGE, TD-SCDMA, and WCDMA/LTE applications.

The SKY18120-11 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 SKY18120-11 is manufactured in a compact, 2.5 x 2.5 mm, 16-pin Multi-Chip Module (MCM) package.

Please note: SKY18120-11 is being discontinued and is not recommended for new designs. The suggested replacement is SKY13404-466LF.


  • Supports quad-band GSM, tri-band UMTS, LTE, or TD-SCDMA
  • Low insertion loss:
    − 1.1 dB @ 1 GHz GSM transmit
    - 0.8 dB @ 1 GHz GSM receive
    − 1.1 dB @ 2 GHz GSM receive
    − 0.7 dB @ 2 GHz UMTS transmit
  • Good 2nd/3rd harmonic performance:
    − –52/–52 dBm @ PIN = +35 dBm (2G low-band transmit)
    − –67/–60 dBm @ PIN = +32 dBm (2G high-band transmit)
  • State-of-the-art SOI process with GPIO logic
  • Ultra-small MCM (16-pin, 2.5 x 2.5 mm) package (MSL3, 260 °C per JEDEC J-STD-020)
