GPS Front-End Modules For Mobile Applications

Source: Skyworks Solutions, Inc.

Skyworks introduces new shielded GPS low-noise amplifier front-end modules (FEMs), the SKY65725-11 and SKY65728-11, designed for use in mobile applications such as smartphones and tablets. Both devices feature high linearity, excellent gain, and superior noise figure to enable design flexibility and high levels of integration. Pre-filters provide the low in-band insertion loss and excellent rejections of the cellular, PCS, and WLAN frequency bands.

The SKY65725-11 is ideal for GPS/GNSS/BDS receivers, while the SKY65728-11 is ideal for GPS L5 applications. These highly integrated modules can be placed closer to the antenna, improving receiver sensitivity that is necessary for mobile devices.

Key features for these models include:

  • Innovative proprietary shielded technology provides enhanced immunity to jammers and EMI
  • Excellent OOB rejection simplifies multi-radio designs
  • Low noise figure provides better sensitivity and faster time to first fix (TTFF) for GPS devices
  • Compact package size: 1.6 x 1.6 mm
  • Single supply voltage and current provides design flexibility and extends battery life
    • SKY65725-11, 3.5 mA, 1.1-2.85 V range
    • SKY65728-11, 3.9 mA, 1.2-2.85 V range
